If the original truck was carburated or used throttle body injection, then you won't have to change out the in-tank pump. Pressure is fine for the IP. It's only the newer multi-port injection systems that use the high pressure pumps. Ran the Buick on the in-tank for about 2 years until it went to greener pastures. Replaced it with an in-line pump from NAPA for about 50 bucks. The new pump draws through the old pump fine. No need to even drop the tank. Kept the chassis fuel filter in place as added insurance, though it is a pain to replace, and used the older style box type diesel filter used in the earlier models of 6.2 trucks.
