Fuel Pressure Test
I have a 1993 GMC 1500 w/ a 350 TBI. I am looking to test the fuel pressure but am unable to locate a port to connect a gauge to. Can anyone tell me if there is one? I have looked at the fuel rails running on top of the manifold to the TBI but there is not one there.

There isn't a test port. I tested my old 89 Suburban a few years back and, if I remember correctly, I had to disconnect the fuel line from the throttle body and use some adapters and rubber hoses that came with my pressure tester to do the test.Gary
