the smaller line is always the return

Not on my car its the other way around, i just firgured it out. 1/4 is fuel feed and 5/16 is returned.

I've never seen that. You better check the routing back by the fuel filter. Somebody screwed something up.

If you're that unsure, disconnect both hoses and see which hose fuel comes out when turning on the key Homer. DUH.:D

And there you have it :thumb:

I have heard of some people switching the lines (which you have to do on both ends) to get lower fuel pressures when running large injectors, the 1/4 line was the bottom limit. this is not the correct way to do it, but if you add a new larger feed line, it can be done. ok, sorry for side track :)

+1 to what everyone else said. Smaller is always the return. If it is not its wrong. You need to fix it if it is.
