CPI install

So i have a 305 mechanical fuel pump carbed pos. I purchased a 350 4 bolt shitty 193, tbi engine. I also scored a cpi unit and can get the multiple injector upgrade cheap as dirt new as well. But the tbi block doesnt have a mechanical pump spot, my tank only has one line going from it so i believe i need a sending unit, 60 psi pump and to wire the harness in to the chassis. Will a tbi sending unit work? I have a 60 psi pump w/ sending unit but it was out of an old truck and is way to tall for my tank. I figured drop the tank since i plan on dropping rear to change carrier to an lsd unit from a 4th gen and new 3.73s. My biggest concern is the fuel lines/pump. Since its a completely different setup. Any tips or how tos apprecriated

Re: CPI install

A TBI sending unit will work; you will just run the higher pressure pump. Buy reproduction or salvage yard lines from down south for a later model with EFI. It's pretty easy to install things when you don't have to deal with bending stuff.
