Leak at fuel pressure regulator
 
Well I am almost done with replacing the injectors on my '90 Z. I put in all new viton o rings in the fuel rail lines. I have the fuel rail and injectors installed so I pressurized the fuel system to check for leaks. I am leaking at the fuel pressure regulator. I have made sure everything is tight. Anybody have this problem and have suggestions?


Thanks

Leaking at the Fuel Pressure Regulator could mean an "O" ring started to leak (installed improperly or damaged during installation).

Ugh.

I went through this. When my old man had it years ago he had a leaky one. I'm not sure what happened or what caused it but he had a local shop replace it and it started to leak again shortly thereafter.

I had that one replaced at a Chev dealership to the tune of 800 ish dollars. It was quite a hassle to just find one and now it's a little nerve racking because 1 going out is weird and 2 going out is almost unheard of.

Re: Leak at fuel pressure regulator
 
Is it leaking internally - fuel dripping into the vacuum hose to intake - or externally - at fuel line connection to FPR?
If internal, diaphragm failure. If at fuel line connection, seal failure.
