When putting EFI in my '57 Sunurban, I want to use the complete in-tank fuel pump/pick-up/floater assembly from a late '80s truck (the same that supplied some EFI parts) in my stock tank. I know I will have to modify a bit!
My question is whether the '80s floater part in the tank will work with the '57 gas gauge in the dashboard? They may not require the same voltage or amps...
If they would not work together for electrical reasons, how can fix this, how can I modify to make them work?
Thanks!
