Is it possible to install a fuel pressure regulator incorrectly? I have hunted high and low to find a picture or text on how it goes in. I do not remember what it looked like when I put my new one in (the fuel rail location) but I have a fuel pressure problem. KOEOff I get 70 PSI of fuel pressure measured at the "out" side of the fuel filter and at the supply line quick disconnect at the engine. The problem is I only get 30 PSI out of the fuel rail schrader valve. Vacuum line connected or disconnected and a slight drop engine running. I am in the process of pulling the plenum/fuel rail back off and look for a crimped metal fuel supply line or an obstruction in the fuel rail somewhere. I am going to check the fuel pressure regulator, but I want to make sure I know what I am looking at. Install pictures or diagram would be great.
have the same problem?
