Tuning Question

[DJay]

Just installed my AccuFab adj fpr.

What is a good "baseline" fuel pressure to start from?

ALSO... this new fpr is a bit taller than the stocker; the vacuum line is a lil kinked trying to reach the top. Is this a prob? Should I install a new piece a bit longer?

As of now (going from memory) FP with line off is 42 and with line on is 47psi. Car seems a bit rich but I haven't run WOT in 3rd yet to see mV's.

TIA; you're the best!

It looks like you have reversed your memory of the pressures. The fuel pressure should drop with the vacuum line connected. So, if you have 47#'s with the line off that is generally to high. It should be around 43#'s with the line off, and drop into the high 30's with the line on. Try dropping the pressure to 43#'s, line off. And yes, if the vacuum line is kinked, replace it with a new longer line.
