How to check fuel PSI??

[slow_90firebird]

Hey guys I was wondering the cheapest / easiest way to check the fuel PSI on a 1993? I just did a piston lift pump upgrade, i used the cummins line, spacer, gaskets, but got the delphi HFP702 pump from oregon fuel injection for $75 to save money.

The truck runs great with the new pump, the problem is that it ran great before also. I cant feel a lick of difference. So either the Delphi isnt performing any better than the diaphragm, or I was expecting too much. Also, the only other small difference is starting up it takes a few cranks now where it started first crank every time before... no big deal tho.

I think I read somewhere that you can use the hole for the bleeder screw that sits in the banjo bolt at the filter, but not sure where I could find a fitting or cheap guage.

I am not looking for a inside the cab deal, just something for diagnosis under the hood. I have an actron pressure tester kit for my TBI firebird and the guage will screw onto any standard schrader valve on most gas fuel rails, if I could make that work it would be great. If not i saw a little guage at autozone made for carb applications, supposed to stay under the hood and reads up to 15psi...

The fitting that goes where the bleeder screw can be had from Geno's...

Get a tapped banjo bolt from Geno's for a 2nd Gen. It will fit ours. Also, you usually don't feel a difference in everyday driving if you had a good stocker before. 2 things most people see are less smoke and more power in the higher (above 22-2500) RPMs.

X3 on the bolt from genos. It's only $7 and it's harder to build one. BTDT. The outlet in it is 1/8th NPT, so it's easy to adapt from it to a gauge.

I ordered my fitting along with some other parts from Genos and will hooking up a fuel gauge on my 93.
