Smelling Fuel.....Damn Fuel Regulator

Piston · 03-22-2001, 03:38 PM

It seems that ever since I replaced my stock fuel regulator on my 94 gt the fuel just pours from underneath the regulator by the fuel rail. I first replaced it by a bbk unit that was returned thinking it defective. I got an aeromotive replacement this has had the same effect. Although the fuel pressure stays up there there is a small leak right underneath the regulator. Does anyone have any idea what I should try to see if it is a defective regulator or fuel rail? So far I bought replacement rubber gaskets from auto zone. i'm getting fed up with my car leaking fuel. Although I was over joyed hearing the thing start again.

probably a stupid question but did you remember to use the new rubber o- ring with the new FPR?

I had a leaking BBK unit. Called them up and was told to remove the FPR and tighten the allen screws that hold the two pieces together. That solved the problem, although I just recently replaced it with an Aeromotive FPR. Make sure the FPR mounting surface on the fuel rail is not bent. Put a little light oil on the O-ring before you install it, and make sure that the 3 screws holding the FPR are tightened down, also check to see as you're tightening the unit down that the flat gasket is seating properly.
SMOKEDAWG - My experience has been that I needed to remove the upper and the fuel rail to easily get at the allen screws for the FPR, although the instructions indicate that you don't need to do this.
