So i have ran into fuel pressure problems. My Fuel Pressure at Idle is anywhere from 24-27PSI and at WOT any where from 32-36, as you get higher into the RPM Range the FP drops slightly. So today i tried to up the FP on my regulator and gas was leaking through the Brass allen head screw fitting. So i screwed it back in ALL THE WAY and it still leaks fuel. Any way i can seal the fitting up?

Did you put pipe dope on all the fittings?

Its the adjustemnt screw that is leaking? They arent supposed to,and not supposed to have sealant.Maybe the diaphragm is tore slightly allowing fuel to leak by?

My suggestion would be to call up Aeromotive and see if they sell a repair kit.

The Aeromotive 5.0 FPR's are notorious for leaking, they probably have a worse reputation than any other brand of FPR for 5.0s.

That's a shame, considering Aeromotive otherwise makes pretty good quality stuff.

If you end up buying a new one, try a Kirban. Most people on these boards run them/recommend them.

X2...I just swapped to '95 fuel rails, and the BBK FPR that was on there wouldn't quit leaking either...I swapped out all the O-rings on it, and still no fix...right now, it's running a stock one, but I've got a Kirban on the way, and I had a Kirban on my early model rails-never leaked a drop, and worked like a champ.

The FPR that's in there probably isn't rated for that kind of pressure. Might be for a carbed application or something.

At full Throttle from 2K RPM all the Way to 5,500 RPM my FP guage is reading 38. Is this right? Or is it supposed to build pressure as the RPMS increase?

No,thats right I believe,the pump is going at about the same speed at all times,the injectors are controling the fuel going into the engine,not so much as the pressure.
