Ken, since you worked for Retrotek, and Greg spoke to the reps on the returnless fuel management system I have a few questions. If it is vacuum based, does the engine need a certain amount of vacuum to operate the system? I have very low vacuum due to my cam choice, but haven't worried about it before due to manual brakes/trans and a double pumper carb. I'm moving to EFI, trying to decide between FAST and the PJIII. The returnless option seems like a simpler set-up for me. I have no factory return line, or vented/baffled tank. I could install this without removing my tank which would be a plus. Except I left the sock off my pick-up, will a simple 100 micron pre-filter cover that need?
