I runs fine until you accelerate hard, then the fuel pressure goes up like it is suppose to, but at about 3500 the fuel pressure drops off to about 25 psi at 4000 rpm and the car leans out badly. We think it might be a bad fuel pump.

The fuel pump hose and clamps inside the tank need to be checked for leaks. It sound like he has fuel bleeding off when it gets to a certain pressure.
I'm assuming the fuel filter has been replaced recently, right? If not, that's the first thing he needs to do. Lee and I just experienced the same problem tonight on a new-edge Cobra with the fuel dropping off eraticly above 3500rpm.
