To Return, Or Not To Return. That is the question.
Can I first start with: I hate buying stuff. Or, really, I hate having to decide what to buy. But here I am. I've decided that I'm going to install a Holley EFI system, with new dizzy. My last problem to overcome is fuel delivery. Holley makes a returnless drop in pump, which means only 1 line running to and fro. However, they recommend 3/8", so I technically should replace my 5/16" with 3/8". (I know, the 5/16" would probably be fine. The FPR is then mounted in the tank, which can be it's own set of headaches, but is a cleaner install. OOOOOORRRR, do I get a Spectra FP, which is also a drop in, but is a return style. Then I could use the 5/16" as my return, and run a new 3/8". With doing it this way, the FPR is on the throttle body.
Is one way better than the other? Why? Which would (or did) you choose? Why?
