TERA PUMP 5th Gen TRFA01 Fuel Transfer Pump with Overfill Protection (2.7 GPM) Universal Gas Can Adapter, 39.4 inch Vinyl Hose, Liquid Transfer Pump for E15, E85, Gas, Diesel & More

UPDATE... 07/06/2025: I just added another star (from 4 to 5 stars)... because as ridiculous as wiping-down this item (after every use) is crazy! I have never done it and the device is still working well. It's a little slower flow, but I think that is because my batteries are starting to fade. No leaks, no problems, EXCEPT the line (and suction-end) that goes inside the gas can be a bit difficult to get in and out of the gas can opening. It's almost like trying to squeeze (or pull) a 2.50 inch microphone through a 2.48 inch opening. So you will get gas on your hands every time you refill the gas can. It's not horrific unless you drive a really nice car, and use your gasoline soaked hands to drive your gas back home. One important thing to remember (after you are done using it)... is to LET OFF THE PUMP HANDLE/TRIGGER, TURN OFF THE POWER BUTTON... and then carefully hold the gas pump handle up and above the gas can while holding the pump handle lever in. Don't worry, (NO GAS WILL PUMP-OUT) BECAUSE YOU JUST TURNED OFF THE PUMP'S POWER. This returns the unused gas left inside the hose back into the gas can. IF YOU DO NOT DO THIS... gasoline pressure can build-up (especially in summer heat with fresh gas). If you fail to do this, you will eventually notice the strong smell of gasoline around the location where you store your gas can. That's not a huge problem if you like the smell of gasoline, UNLESS you store it in an unventilated area near a water heater pilot light, or some other sparks or flames are nearby. __________________________________________________________________________ PREVIOUS PRODUCT REVIEW BELOW: I HAVE NOT (and will not) REMOVE & WIPE DOWN THE PRODUCT AFTER EVERY USE, but it's still working well, SO I ADDED A STAR. I'll try to update again after one year of use. This pump is a great idea and seems to work well, BUT I CANNOT BELIEVE they expect me to remove the device and wipe it down with a cloth AFTER EVERY USE. This sounds dangerous because you will obviously have gasoline on your hands, as well as gas vapors, and a gasoline soaked cloth to store or dispose of. Hopefully nothing sparks and you don't have any gas appliances in your garage, because a pilot light can ignite gas fumes or vapors. I sent the company an email to confirm "remove after each use" was what they are asking customers to do. They replied back quickly (which I appreciate) and said "we don't recommend leaving the pump in contact with gasoline due to the fumes possibly eating up the hose" and THAT they would get with their team to make sure the Amazon description states this in the future. I then suggested they just make all of the plastic parts from High-density polyethylene (HDPE) which is what plastic gas cans are made of... it makes sense to me anyway. Again, I really like this product (so far), but not-so-much if I have to come into contact with gasoline every time I use it. If that's the case, then it's probably not for me; because that gasoline smell stays on your hands quite a while, even after washing them several times with soap.

Our local grocery store started offering discounts on gas based on grocery purchases - substantial discounts. But, limited to 20 gallons of gas. My car only holds 14 gallons when near empty so I was leaving $12 or more on the table everytime I filled up with points. I had an old 6 gallon tank and got the bright idea of putting 14 gallons into the car and the remaining 6 into a red gas can. Wonderful idea until I tried to pour gas from the 6 gallon can into the small spout of the car... and had gas dripping all over. What a mess. I got it done, but holding 6 gallons in the air gets tiring after awhile. I wondered about a pump and found this one advertised. I ordered it and received it about 2 days later (very fast shipping). I had to add 4 batteries (AA cells) to the control module. The pump is sized to screw onto 4 different openings of gas cans. Unfortunately, my real old plastic can was not one of the supported sizes. I hung the pump in the opening and tried pumping into my car. It really worked! I could see (and hear) gas surging through the translucent tubing. In about 2 minutes I had pumped almost all of the gas from the can into the car. No gas was spilled in the process. I was so impressed, I went to my local farm and home store and bought a new 6 gallon plastic gasoline can ($14). One of the included adapters was a perfect fit. Now the pump is screwed into the new can and it looks real slick. Looks aside, the performance is what impressed me. There is a grey plastic pump (think the size of a squat cigar) that has rotating blades on the end. This impeller sucks up the gas and forces it through the tube into your cars tank (or tractor, or snow blower, or pressure washer, etc) when the "on" button is pressed. Gas continues to be pumped until you push "off" or the sensor on the tip of the nozzle detects gas flowing back. This is going to be perfect for filling the tractor where the pump nozzle can be clipped vertically to the fill tube for the tractor (or other yard implements). Gone are the days of pouring gas from a can, through a funnel, into a snow blower tank only to have it bubble out and make a huge mess when the tank filled sooner than expected. Now, leave the gas can on the floor and pump it right into the snow blower & let it stop when the tank gets full. When done pumping, hold the nozzle up high (in case any gas is left in the tube can drain back into the tank) and insert the nozzle into a hold on the side of the pump. This keeps the nozzle high (prevents dripping) and clean. While it calls for 4 AA batteries, this pump uses them in parallel. It can actually run on just 2 AA batteries but I think it pumps faster when all 4 are used. I wondered why they didn't use C or D cells, but that would have made the pump housing much bigger. So this works well. Operating temp range is cited to be 5C to 45C (41F to 113F). I keep this in my garage where temps can get down to about 10F. When I tried it, it worked fine. I don't have a lot of experience using it with low temps though. I was also wondering how much gas this pump would leave in the gas can. Turns out, not very much. I removed the pump and poured the remaning gas into my car - I'd guess it was about 1/3 to 1/2 cup that the pump did't get - probably because I didn't tilt the tank so the gas settled in a corner along with the pump. This review is based on my initial impression which is very positive. I can return to update this review as I gain additional experience with the pump through rest of this winter and the seasons yet to come.

Works great, quiet, shuts off when full... recommend!

I wrote a more thorough Amazon review for this product, but there was a glitch and it got deleted somehow. I don't have the patience or enthusiasm to re-write that whole thing, so instead I am trying again with just some basic facts and considerations. - This is an electrically powered fuel transfer pump. It is powered only from "AA" cells (batteries), and can work with just two of those, but for best pumping power & battery life you can install four of them. For year-round use, I suggest installing Lithium type cells, such as the Energizer Ultimate Lithium brand, because these a tolerate wide temperature range better than alkaline types, and don't have the problem with leakage that unattended alkaline cells do. - The battery compartment is the center piece of the assembly, and contains the cells/batteries, the power ON and OFF pushbuttons, a discharge nozzle storage chamber/dock, and it attaches to the opening on most common North American brands of 1 gallon and 5 gallon plastic fuel cans. Three adapters are included with the product; one of them fits my "Blitz" brand 1 and 5 gallon cans, another of them fit all of my "No Spill" brand cans...I don't know which brand(s) the third one might fit (maybe the Scepter brand?). You find the adapter that fits your can(s) and screw it onto the opening of the can, then screw the battery compartment's threaded fitting onto the adapter. - A flexible intake hose extends from the battery compartment, through its threaded fitting and the adapter, into the fuel can. The actual pump is permanently attached to the end of the intake hose, and is supposed to either hang inside the can or lay on the inside bottom of the can. The flexibility of the hose and the size of the pump housing is such that it will lay on the bottom, more or less on its side, if you are using a 5 gallon can. On a 1 gallon can, the pump and hose will have to fit however it can, but might not have the pump inlet right at the can's bottom, limiting how far down you can pump it empty. On a can larger than 5 gallons, the pump might just hang at the end of the intake hose, without touching the bottom of the can, so there might be some unpumped fuel remaining. - The electrical power for the pump gets to it (from the battery compartment) via a fuel-safe cable that is inside the intake hose. Regardless of how many batteries you install, the maximum voltage in this cable and at the pump is 3V. It is supposed to be safe to have the pump permanently installed on a fuel can and operated as-needed. - Unlike most modern plastic fuel cans, which have a ratchet-type mechanism to prevent accidental unscrewing of the nozzle (and this feature is also supposed to make the cans "child proof"), the threaded fitting and the can adapters of this product do NOT have any such feature. Take care where you locate the fuel tank(s)/can(s) being used with this pump! - The pumped fuel exits the battery compartment via another hose (the discharge hose) which is 34" inches long. Some of the sales text associated with this product suggests that this hose is elastic, or can accordion or telescope to be shorter or longer; I did not find that to be true.....it is 34" inches long, period. - At the end of the discharge hose is a 4" long discharge nozzle, and this is the part you insert into the opening of the fuel container you are trying to send fuel to. This can be the fuel tank opening of an automobile, the top opening of the fuel tank on a lawn mower, snowblower, small garden tractor/riding lawnmower, etc. The nozzle does not have any kind of valve, and does not have any kind of manual control for fueling (as does, for example, the fuel nozzle that gas station pumps have on their hoses)...it is just a 4" long plastic tube. There is a plastic clip molded to the side of this discharge nozzle, and it is intended to hook onto the lip of automobile fuel tank openings, or to the threads on the fuel tank openings on tanks of lawn mowers, etc; so that the nozzle does not accidentally fall out of the tank/can openings during fuel transfer. Pressing the end of the plastic clip springs it up just enough to allow it to disengage whatever it was hooked onto. - Inside the end of the discharge nozzle is some kind of electronic sensor; I think it is just a tiny electrical probe that detects the conductivity of the fuel when it comes into contact. It is connected to the battery compartment via a able that, like the intake hose, runs inside the discharge hose. When fuel touches or comes close to that sensor, it signals the battery compartment circuit to stop the pump. Both the ON and OFF pushbuttons are momentary types, so this sensor acts like a secondary OFF button. In my experiments, the sensor works quickly and well, but see my caveat below. When you are not pumping fuel, the discharge nozzle docks into a tubular chamber on the battery compartment, and a raised plastic ring at the opening of the chamber gives the nozzle's clip something to hook onto. - There seems to be nothing about the design of this product to prevent siphoning. The included operator's manual advises to always have the source tank/can at about the same level as the destination tank/can. This does not mean that the pump cannot push fuel up to higher levels; indeed, it can raise fuel up the discharge hose even if that hose is held straight up vertically from the fuel can that the pump is inside of. This caution appears to be to minimize siphoning. Even if there IS some kind of anti-siphon feature that I missed, there is still the issue of "what happens to all the fuel that is already in the discharge hose when you turn the pump off" (either by the OFF button on the battery compartment, or automatically when the sensor detects fuel at its end)? The answer is: if the discharge hose is horizontal, or if it is sloping upwards from the tank/can where the pump is, the fuel will either stay in the hose or will run backwards into the pump's tank/can. BUT, if the discharge hose is sloping downwards, as soon as the pump is stopped all the fuel in that hose will immediately run out through the discharge nozzle. EXAMPLE: I had a 5 gallon gas can, with the pump inside, sitting on a shelf 2 feet above the floor of my garage. The discharge nozzle was clipped onto the opening of the fuel tank of my walk-behind lawn mower (which was lower than the gas can where the pump was). When the mower's tank got full, the sensor immediately stopped the pump, and then all the fuel in that 38" (34" hose + 4" nozzle) of hose (roughly 1/2" inner diameter) ran out into the lawn mower tank, overfilling it and all that volume of gas ended up on the garage floor. Since that happened in about a second, I did not have time to unclip the nozzle and raise it up above the level of the gas can, which would have stopped the flow. It is better to use this product such that it is pumping at least a little bit higher than the level of where the pump itself is located. - This product seems to me to be of decent quality. No part of it seemed cheaply made. But I do wonder about how well it will hold up over time. - I recommend always rising the discharge nozzle above the pump's tank/can so that all fuel runs back into that tank/can, rather than leaving it inside the hose(s). And also always store the product with the discharge nozzle docked into the battery compartment chamber intended for this purpose, because this will eliminate any chance of siphoning causing a fuel spill while not attended. And this is a "pretty" looking product, with attractive red and green buttons that a child might want to push...if they push the ON button while the discharge nozzle is docked in its chamber in the battery compartment, as soon as fuel starts coming out of the end of the nozzle, the sensor SHOULD immediately shut the pump off again. But best to locate this away from where any children will be while unattended.

I opened the box the TRFA01 and looked at the pump before me. The flexible hoses are clear and of good quality. The power motor is assembled at the end of the suction hose and attached securely. The pump wiring runs internally inside the suction hose from the body of the battery holder/control device. No wiring is exposed. The unit is lightweight and the adaptor caps are easily attached. Four AA batteries are required but not included. The discharge hose is firmly attatched to the battery box/control device. The output of the discharge hose is through a "nozzle" that should be into a recess in the body for safe storage. The nozzle contains a sensor to stop the pump when fluid touches the sensor in the discharge nozzle. All these connections and fittings are well made and professional. I installed my four AA batteries and ran the pump for a few seconds dry. I was surprised to find a noticeable discharge of air from the discharge hose. I shut down after this short test and packed the pump carefully away in it's shipping bag. This is exactlly what I was looking for! I have a diesel fueled truck, and I always carry a 5 gallon fuel can with me. I use these 5 gallon fuel cans every few months to allow for fresh diesel to be stored. Well at 72 years old, the darn 5 gallon cans are getting heavier! No really! Trying to stand for the five minutes it takes for a diesel can with no air bleed vent to empty is tiring for me. I don't like the smell of the diesel I spill down the side of my truck, or the soaking it sometimes gives my shoes. Trying to hold the safety nozzle turned and open is another feat of gymnastics my hands can no longer perform for the time required. I've used all kinds of gas cans, the 2 and 5 gallon round, the NATO military style with the 3 inch jug mouth with an attached flex spout, the 1 and 2 and 5 gallon plastic cans. Always managed to spill a few drops of gasoline, but nothing you couldn't wipe up with a rag. Then they decided this was unsafe and we consumers would be better served with these new safety caps that make it nearly impossible to refuel from any size of gas can. I have never spilled or wasted so much gas or diesel in my 60 years of dealing with gas cans! This battery operated pump is just what I need. I can elevate the can onto my vehicle doorstep and "PUMP" the fuel into my tank without spilling any amount. I can secure the empty can and then once home clean out the pump system, remove the batteries, and store it away for the next use. A few quick tips. Buy a 4 pack of good AA batteries and keep "buried" in your vehicle as spares. Elevate the gas or diesel can as high as you can before transferring the fuel. Pumping "downhill" goes faster withh less wear and tear on the pump. Avoid leaving in sunlight as this will "accelerate" the decomposition of the plastic hoses. Read the Instructions! Don't smoke! Vehicle should be off. Be safe not sorry!

I really love it when a product completely solves a problem for me. I have a diesel powered utility tractor that we use around the property. Since we do not have a diesel storage tank on site, I bring the fuel home in 5 gallon cans. In order to fill the tractor it requires hefting the can up to shoulder height and then holding it that way as the tank is filled. This is extremely inconvenient and I have been looking for an easy way to fill the tractor. On occasion I have actually pulled it onto a trailer and hauled it to the local gas station. With this pump, I simply put it in the 5 gallon diesel can, place the can on the floor of the tractor and in a couple of minutes have got a full tank. I have seen a number of negative comments which caused me to have second thoughts about whether I really wanted to order this product. One reviewer complained that the automatic shut off did not work. Mine works flawlessly. Initially I actually thought it was malfunctioning and had shut off prematurely but when I looked in the filler pipe I realized that the pump filled the tank so quickly that it simply shut off before I realized it was full Several reviewers have complained that the pump "leaks". It actually does not leak. There is an anti-siphon hole in the bottom of the pump which, if mounted correctly, would be located inside the neck of the gas can. The purpose of this is to break the suction to prevent siphoning if the can is at or above the vehicle fuel opening. If it were not for this hole, fuel would continue to siphon out of the fuel can even after you shut the pump off. When the pump is running, as a result, some fuel will splash out of this hole. If the pump is properly installed on the gas can you will never even know it because it goes right back down into the can. The instructions clearly state that you should not try to use the pump unless it is screwed into the gas can. If you simply try to place the siphon tube in the can without screwing it on, fuel will splash out of the anti-suction hole and make a mess. All you have to do is follow the instructions and it works fine. One reviewer complained that the hose was too short. Well, yes if you have a boat you cannot leave the gas can on the dock and expect to be able to fill the tank of the boat. I do not think that is a reasonable expectation. That is not what the pump is designed for. The hose is plenty long to reach the average fuel inlet on most vehicles. Is the fact that you have to use one of the included adapters a problem? For me not at all. I leave the pump mounted on the can in between uses. There is a socket on the pump housing to place the nozzle in order to keep it clean when you are not using it. It is true that it does not provide a completely spilled proof seal however none of my fuel cans have a spill proof seal anymore since they started putting those ridiculous safety spouts on them. Every single 1 of them has malfunctioned.In short, this is a $59 fuel pump not a multi-thousand dollar fuel transfer system. I think it does an excellent job for the price and if you have lawn equipment that you regularly refill from an unwieldy 5 gallon can, this is a very good solution. I cannot comment on the longevity or durability of the product since mine is relatively new but if it does show premature failure, I will be certain to post an update to this review.

Update 7/7/2020: My attempt to seal the wiring tube and fuel pump line connection to the controller failed. It isn't leaking from where I thought, or if it was, the Seall All stopped that leak and exposed another. Chances are, it wasn't leaking where I thought. I popped off the battery compartment half of the controller housing and ran the pump. The leak was not happening inside the controller housing, it's leaking from the cap in a way that bypasses the rubber cap seal. The only thing I can conclude is that there is a crack or some other leak path in the plastic elbow that's part of the lower half of the controller housing. There is no visible damage and the leak path is unclear. I am going to install a fuel line hose from the pump to the nozzle and I'm just going to tie wrap the controller to the fuel line and call it a day. I intend to run the wires on the outside of the fuel line and pierce the fuel line near the pump to get them inside. I'll use Seal All to seal the hole where I insert the wires through the fuel line. It'll be a total hack job, but it should work. I bought this thing near the end of last summer and only used it once. It worked that one time without leaking. It's been sitting empty for 10 months and was kept inside a shed during the winter. I don't know if cold temperatures cracked it. I can't imagine that happened since it was completely empty of fuel. Regardless, it's too late to return it and I need it to work, so I'm going to make it work and I don't care if I can't use it as a fuel can cap. Original Review 7/5/2020: I'd give this a 5 star review if it didn't leak like crazy. The pump itself works great. The weakness is where the pump motor wiring goes inside the fuel pump tube. The pump wiring is inside a narrow plastic tube that's pressed into a slot in the tubing flange on the control unit. The fuel pump tube slides over the slotted flange where the pump wires are. There is a plastic ring that's pressed in place around the fuel tube and seals the fuel tube against the tubing flange and the wiring tube in the slot. The problem is that the wiring tube in the slot creates a leak path if it shifts in the slot even a tiny amount. The plastic ring that holds the fuel tube in place on the control unit is easy to pry up with a screwdriver and the fuel tube is easily removed from the flange. I'm going to try and seal the wiring tube slot and the fuel tube with Seal All. Hopefully that will stop the leak. IMO, the mfg should have run the pump wiring from the controller on the outside of the fuel pump tube instead of the inside and put the wiring entry point on the pump end of the fuel tube instead of the controller end. It doesn't matter if the wiring causes a fuel leak at the pump end because the leak would be contained within the can and nobody would notice. However, by inserting the pump wires into the fuel tube on the controller end, the leak path bypasses the rubber cap seal, goes through the cap threads, and then all over the outside of the fuel can. The thing is, the leaking barely affects the pumping volume. It pumps great even with the leak. If the leak was totally contained within the fuel can, nobody would notice. However, with the fuel leaking at the controller end it winds up making a huge mess. Even if the Seal All stops the leaking, I'm not going to give this more stars because I shouldn't have to fix this design flaw.

I love the quality, function and ease of use of these pumps. They work really well it makes gassing up the boats and snow blower a breeze. They are very easy to use and they fit my 5 and 6 gallon fuel cans perfectly. I normally keep my fuel cans in the garage but the one time I accidently left the gas can out overnight a squirrel or chipmunk chewed through the hose, which you cannot replace or repair. Lesson learned. I love mine and wouldn't use any other pump.
