Need help w/fuel pressure
I installed a used BBK fuel regulator and my pressure wouldn't drop below 65 PSI. I thought it was a bad regulator so I bought a new Kirban and installed it today. My fuel pressure is stuck at 65 PSI and wont go up or down. If the engine is running and I open the throttle the pressure will drop to around 55 PSI. What could be my problem? pinched return line? oversized pump? Please help, I'm open to any suggestions.
Thanks,
Chris

Suggestion........ disconnect the fuel return line from the fuel rail, prime the fuel pump engine off, and confirm fuel pressure + fuel flow from the return line connector at the rail. LUK

are you disconnecting the vac line while setting the fuel pressure?

RE: Need help w/fuel pressure
One other reason I don't think it's the fuel gauge. I had a guy at my brothers work do an emissions test when I got the new motor in. All the readings came back like it was running real rich, so I assume with that and the pressure reading high that the pressure MUST be high. LIke I said though I'll check the return line then the gauge.
Has anyone ever experienced a problem with the return line?

My prayers have been answered, thank you God!
apparently I kinked the hose at the fender when I did my engine swap a couple weeks ago. I fixed the line, adjusted my fuel pressure, adjusted my TPS and timing and now the car is running like a beast.
Thanks for all the suggestions guys. Now it's time to go enjoy my new motor with the top down!!!
