I want to use the loctite 574 to seal a vw type 1 case. how many 50ml tubes you think i may need?

1 should be plenty. I assemble at least 2 Porsche 944 engines with 1 tube and that's rolling (small velour roller) the lower crankcase girdle and oil pump per engine. It doesn't take much quantity (thus the roller) since this is designed for .01" gaps of imperfection between the 2 halves. You can purchase a short nap velour roller with matching miniature roller tray can be purchased at local hardware or Sherwin Williams. Roll both halves of case. Good thing about anaerobic sealants is, it won't cure until parts are assembled.

Is this "gasoline" resistant?

I would lean towards yes, oil and gasoline resistant. I use on corners of gaskets where rtv would be too thin to hold.
