Electric Fuel Pump

Most sources say you must put it close to the tank and lower than the tank, but I bet they haven't experimented. My electric pump works fine in the engine compartment in 2 Mopars (A body & C body), low on the inner fender. One has the factory 5/16" supply line and the other a custom 3/8" supply. Both have a bypass regulator with return to the tank for EFI. One is running 22 psi at a Holley TBI and the other 9 psi for a carb (EFI later). One pump is a Walbro (225 lph I recall) and the other a Holley gear-rotor (have used a Ford external pump too). If you have a return line and reg in-line with the carb, you can use an EFI type pump with a carb.

If you put it on the rear frame rail like most people do, it will probably make a racket around the rear seat. I did that first and tried rubber isolators, etc. I hated that location too because it is very hard to access if problems on the road, plus a grubby location. I also had a pusher pump back there once, which caused more problems than not (starved the main pump, etc). I saw how gas poured from the supply line in the engine compartment, so figured that wouldn't starve the pump, and it doesn't. I have a simple carb type pre-filter on the inlet and a fuel injection type filter on the outlet of each. Search my posts for photos and more.
