[quote=RobbMc]Another option is our PowerSurge. The only drawback is that it requires a 1/4" return line back to the stock tank. Some cars came from the factory with a 1/4" return line but some didn't.

RobbMc, I'm curious how the power surge system would work when installing a gen 3 hemi in a 72 Challenger.
I don't have a fuel system installed other than a stock tank.
The sending unit has a 3/8 line with a 1/4 return so good to go there.
There is no fuel pump on the hemi or in the tank.
I am going to have to do something. Either one of these new tanks for EFI or maybe your system.
