Review: Great Value - Great product, works great
Review: Quality Check Valves - They work well for letting fluid through. They dont flow at first, but if you put some fluid through and add a little pressure they will flow. Once they have fluid in them they continue to flow. I think they just need the initial lubricity then all good.

**Q: Would this valve be effective in a air/vapor system?**
A: yes, the valve can works in air system

**Q: Can this be used on a submersible 600gph water pump for the basement?**

**Q: Do you install before fuel pump or close to carburetor**
A: Hi, it depends on your application, it usually installs close to the tank but you can put it closer to the fuel pump if you want. in any event it goes before the fuel pump as your trying to stop flow back.

**Q: Will this fit to Mazda Protege 2.0? Reference: 8574-20-309**
A: This check valve will fit any 1/4 or 6mm fuel line.
