Thanks for the quick reply! We have a 4 bbl intake, I knew the trans would need some mods/switches/wiring, didn't know what the computer controlled other than injectors & spark timing, do we need to leave the computer in the truck for anything? Can we put a standard fuel pump pickup with float/sending unit in and hook it up to the existing sending unit feed wire? , (I have a new one for a '81-'87 carb application) didn't know if the Ramcharger fuel tank itself was different between the earlier carb models and the later TBI modelsI just don't want to remove anything that is going to bite us in the butt further into the conversion!
