Hi.. car has been shutting off intermittently lately, so I put a fuel pressure gauge on the fuel rail and I'm only reading 26psi at idle and 32 psi w/ regulator hose pulled off.. what should the fuel psi be at an idle?? Replaced regulator w/ aftermarket non adjustable, do I need a fuel pump? And what kind of pump should I buy??

Why would you replace your fpr w/ another non adjustable one? Try a fuel filter before you condemn the pump. Pressure should be 39psi.

I regret not putting an adjustable fpr on it, but it was the only one available at the time I had it torn down. I replaced the filter last year (150 miles ago).

has you car been studdering while driving? will it still idle fine?

No shuddering and it idles fine.. about 750-800 rpm.. but when I give it a little gas at an idle it does take a little bit for it to come back down to an idle.. like a few seconds..

How does it run down the road. Overall Drivability?

It runs really good!! I mean for a stock 302..? I don't feel the pump cutting out or anything under a load either.. You should read my other post... cuz I checked the psi BEFORE I fixed the stalling problem, and maybe that had something to do w/ the pressure??

PRO50SC

So other than low fuel pressure, the car runs great? Is that correct?

89SilverBullet

Yeah.

How about mine....not to hijack....mine will studder under a load like a *****(can't drive it), but will idle and rev in nuetral fine..havent check fuel psi yet..sound like the pump?
