Fuel Pressure Regulator Problem/question?

[Lance-W]

I'm trying to get my 69 Camaro LS conversion started for the first time. Fuel is not getting past the Vette FPR. It's making it to the FPR and it's making it back into the tank via the return line but it will not come out the feed to the engine. I have it plumbed correctly (3/8" from the tank, 5/16" return to the tank, and the single 3/8" line to the fuel rail. The pump is the GM one that comes in the Rick's tanks. I can hear the pump running and there's pressure on the return line. Am I missing something simple here? Anybody got any ideas?

Did you purge the air in the system using the valve in the end of the fuel rail? I flushed my fuel line before connecting it to the fuel rail and then used the valve to get the air out of the rail. Not sure this is necessary but that's what I did and it started right up.

I have the fuel line dis-connected at the rail. My car has no Schrader valve at the end of the rail. No gas........

Try swapping the pressure and return line.

Positive you have the inlet and the return hooked up correctly? It could be a faulty FPR. Nothing is perfect.

On the Rick's tank one fitting is blue and one is silver. Anybody know which is which (feed or return)?

Try swapping the pressure and return line.


Yup, That's what I'll try in the morning if I can't find a sure answer tonight. It's plumbed with hard lines. I'd like to make sure before I start re-plumbing.....
