I'm working on converting my carb to a TBI, and I'm trying to get away with an in-line fuel pump instead of modifying the tank. I see that the Holley pump wants to be below the fuel level in the tank to get a good gravity feed. But then, what happens if I'm going up a steep hill? The gas will be way below the fuel pump, is the pump going to fail and choke off my system just like a carb (or worse)? What does it take to convert my whole gas tank to an EFI style with in-tank pump?
