<x-flowed>>If you have a pressure gauge that you can connect to the fuel rail
on the engine, the best way to diagnose this is to take it for a drive with someone watching that gauge. It should hold at 28-30 psi, but if the pump is having trouble pulling in enough gas you will be able to see the pressure drop as you put load on the engine. Once you fix the problem you will see a fairly constant 28-30 psi.
That's not real easy to do for those of us who don't drive squarebacks :/ To test my pump for consistent pressure while driving the fastback, I just made an extra-long hose extension for my gage out of fuel line hose. I ran it from the engine, along the outside of the car, and to my lap.
