I'd keep the electronic pumps and put a regulator on it (since it's already there).

Why not keep it fuel injected?

It would be easier and more economical if the truck is currently setup as a TBI to just drop it in. 
If it currently is setup to run a TBI, you are going to have to buy new fuel return/supply lines EFI rated to feed the carb and put a regulator inline.

Unless its gonna be a hot rod, listen to these guys and keep the TBI.  I have many regrets about the choices I have made for my truck, not the least of which was keepin' it carb'd.
