Help! I just install a aeromotive FPR
 

I am getting 40psi and wend I hit the gas it drops to about 35psi.

no matther what I do I cant get it to go over 40psi.

I try adjusting the fpr and it still is at 40psi tops.

Fresh air intake
down pipe
mide pipe
cat back
pettit ecu
gredy stock mount ic
gredy elbow
gredy bov
aditional oil coller ( like r1, I have a 1994 touring )
pulley set
no air pump
14 psi boost

You might have a clogged fuel filter or bad pump.

Open your Factory Workshop Manual and go to Section F. Do the dead head pressure test where you block off the return from the regulator then power the fuel pump for 5 seconds. Fuel pressure should shoot up to at least 70 psi (check worshop manual for exact minumum pressure) but with a healthy pump will be more like 110psi. After power to the pump power is removed watch the fuel press., it should not drop below 20 or 25 psi after 5 minutes (again verify these numbers with the manual)

Do a search for "low fuel pressure" or similar phrase, this problem was dicsussed in the last week or so.

thanks jack but i allready try this and got over 100psi.

I will do the search.

Describe the path of the fuel as it flows through your system. Perhaps the issue is how it is plumbed.

Why do you need a rising rate FPR? WTF:D You read this board to much.
IMO

The Aeromotive FPR is not rising-rate, it is 1:1. But yeah, why did you install the FPR in the first place?

maybe he's planning to up the fuel pressure to get some more flow

My stock fpr was bad so wtf, the problem was the relay I replace it,works fine now.

My exhaust temp was some what hi so I put more fuel presure and it drops a bit ( anything to avoid another egine blow up).
