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 Tim Edstrom |

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. |
