So First of many questions....will my factory in tank fuel pump be enough of a lift pump? factory was a tbi 350.

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.

If you're going to run both the electric and the mechanical, you might want to switch to a piston lift pump. 15 psi going in to a diaphram pump could fill the crankcase pretty quick should the diaphram go bad.
