EFI FUEL SUMP PUMP SYSTEM ?

AndyF said

Your best bet is to just put a pump in the factory gas tank. There are kits from Holley that drop right in. The regulator is internal to the tank so you don't need a return line. The surge tanks mounted in the engine compartment are a hassle. That was a concept that seemed like a good idea originally but once people started making drop in pump assemblies for older cars the surge tank approach hit a dead end.

You can either sell this Edelbrock kit and go for an intank returnless set-up like AndyF recommends or feed this system with a stock mechanical fuel pump or low pressure electric pump.

This Edelbrock external sump/surge tank system already has a returnless electric pump inside it, so it needs a second low pressure pump to feed gas into it. Most EFI pumps supply too much pressure for this sump/surge tank system without a regulator and a bypass.

Surge tank systems are becoming even more developed and readily available to the aftermarket, especially in high powered modern EFI cars due to the high G-forces they can generate, which leaves even the best modern fuel tanks putting air in the fuel system under hard use.
