Does the CFI FPR use a vacuum signal to work? There is no vacuum line on top of it like on a 87-93 Mustang.
I am wanting to install an adjustable regulator from a Mustang, it is a direct bolt in.
I don't know whether to:
a. leave the FPR uncapped (but maybe this will cause a vacuum leak)
b. cap the FPR (so the FPR will not read vacuum and maybe it will not work properly)
c. run a vacuum line from the FPR to a vacuum source (but the CFI unit's stock FPR doesn't have a vacuum line to it so maybe this is irrelevant?)
Anyways, this is my line of thinking.
I see about 38-40psi at the rails right now.
Maybe with an adjustable regulator I can raise that to 41-43 and possibly richen the air/fuel mixture . AFR gauge reads lean after 3000rpm at 1/2 throttle. Interestingly enough it evens out at WOT, but ideally would like to see stoich at all throttle positions.
Any comments welcome, yes I'm still trying to make this CFI aka toilet bowl injection move out of its way.
