Re: How to check for a faulty FPR (Fuel Pressure Regulator) and replace it

Frustrating! I really don't want to pay someone else to do this since the part itself is simple, and easy to see.

Thanks for any insight!
I agree with you that it is a dumb design, but you do not need to remove the rail to replace the FPR. I did lift the rail when I did it first time (2 yrs ago). But now I know how to do it without lifting the rail. I used a torx (I forgot the right size, I think it is the same as that holding the fuel rail near the inlet and outlet) bit and a small wrench to turn. There is enough space to stick a torx bit there. Not too bad.

Yes, the aftermarket FPR didn't last long, only for 2 yrs and started leak! Now I installed one from ACDelco.
