Fuel pressure regulator question.
I had a holley FPR, single line in, 2 lines out. I blocked off one of the outs with a filler, and ran a line for my carburetor feed. The return line for the tank, I made a filler by brazing shut a piece of 5/16 hose with the special end for that type of flex line.
Is this going to be okay? I did reuse the charcoal canister so I do have a vent, but I do not have a return line to the tank.

Nobody knows?

Re: Fuel pressure regulator question.
ok. you will need to run a return line. otherwise you may get too much pressure.

What I may do, is use a 3 prong fuel filter (My 86 plymouth has one) and use the 3rd prong to my return line.. For 7$, it's the easiest way.
