It is not a PK/UP but it is on 1 ton axles...
I just finished up a GM 5.3 swap into the truck and I replaced everything from the fuel tank to the fuel rail on the motor with new parts. The fuel system is all plumbed in -06 Aeroquip socketless hose and -06 socketless fittings. I replaced the tank with a brand new tank and sending unit for a 1991 Jimmy and put the pump in the tank. I used a Holley/Walbro 255 LPH in tank pump and a regulator/filter from a 99 to 03 Vette. I am the 4th owner of this truck and this truck is an original Arizona truck so there is very little rust on it at all.
