fuel pressure spikes
1999 Whipplecharged 502 MPI. I am used to seeing 43 psi fuel pressure at idle and 50 at WOT on my Gaffrig electrical gauge. Today I get 45-50 at idle and spikes of 70-90 psi when I open the throttle. What could be causing this????? I would really appreciate any help.

Re: fuel pressure spikes
check the other thread about this called "skyhigh fuel pressure" also hook up a mechanical guage first and make sure you dont have guage, wiring, or sender problems before you get too crazy with it.

Re: fuel pressure spikes
Checked the wiring to the gauge. Embarrassingly enough, it turned out to be a loose spade terminal hanging on the fuel pressure sending unit.
Thanks Hillbilly.
