Any body here have an Autometer Fuel Pressure Guage on their LT1? After first installing it it ready a constant 60 Psi. Now after finally taking a look at the wiring, turns out that one wire had popped out while I was putting the kicker panel back on.
So now that it;s all wired together, I'm getting what I think are wierd readings. At idle, it sits @ 60psi, WOT @ 70PSi and when I let off the gas it drops straight to about 15psi?Then when I touch the gas it goes straight to 70 again?? Is this normal????:confused: :confused
thanks guys:

are using an adjustable fuel pressure regulator?
do youhave the vacuum line from the intake plugged into the regulator?

No I'm not using a fuel pressure regulator, but do the readins sound right?
I have an autometer electric FP gauge
on a normal fuel regulator it should read ~40 PSI , (39 - 43 depends if you have the vacume hose connected)
If you have a blower and FMU it will read much higher as you add boost.
60PSI sounds very wrong

ok, I've checked the wiring, everything is as it should be. The guage does movbe according to when I press the gas. However, The readings are way off. This makes me think, either the guage is messed up or my fuel pressure is messed up. Any suggestions?
borrow someone's mechanical guage and see if the problem is with your autometer gauge or with the car

either that or your fuel pressure regulator is shot

That is weird I just put one in Perry's car today, and well the wiring can't be wrong since it is just a plug in harness, unless your's is different. I would think the problem is going to be your fuel pressure regulator. His read at 40psi but then the battery died on us, he is running a Aeromotive Fuel Press Regulator.

ok now for the stupid question. Where is the fuel pressure regulator and how would I know if it is screwed?;)
I gotta admit that having the needle actually move now and being able to match the orange dash lights almost perfectly, it looks pretty sweet at night.:cool:
