it should be the same as a lift pump on the block. but the pump in the tank is just as bad to fail as the ones on the block. If you plan on keepn the truck, id upgrade the fuel system. Thats the only thing bad about the vp trucks. Loose pressure, loose your Inject pump

The spec calls for 10PSI, regardless of what lift pump you have. In your case, I'd be wiling to bet the pressure is dropping when you mat it.

I'd get an Airdog or FASS system and a fuel pressure gauge ASAP. FASS makes a reasonably priced pump only kit that works nice.
