Well, i have also converted a 92 tbi truck to a 91 5.9. I am using the electric pump and i also have the factory lift pump on the engine. It seems to run ok right now. We'll see what happens when i get it on the road. I dont think it has too much pressure though, somewhere around 15psi.
92 chevy 4x4 91 non intercooled engine nv4500 valair clutch, full fuel screw turned 2 turns, slightly ground fuel cone, 366 spring, stock baby h1c , stock lift pump, timing to head and autometer ultralite boost and pyro. 17 second race truck!!
