OK in another thread I had decided to run a return line for the fuel to a fitting in the filler neck to avoid several other things.
How big does it have to be.
I have an large supply of 1/4 stainless with a .120" hole in it we use for injector line and we have several benders. Is .12 enough to get the dumped fuel back to the tank or should I buy something bigger. Seems a little small to me but what has been used in the past.
Thanks-
Yeah, sounds too small on the ID.
I just checked a random set of SS lines in the garage. These are not from a RBV but I'm sure from some Ford gasoline application. Both supply and return are around 5/16" (8mm) OD and I'm guessing the wall is a lot thinner than what you're describing. So a lot more internal cross section in the factory return compared to yours.
