I guess the principle is the same for EFI or carb as in my case, supplying adequate fuel at all times to the engine.

I have an alloy foam filled tank with two flexible pickups with large gauze filters, set in alloy cannisters with a slot for intake, sucking the fuel up is two little electric V8 holden pumps which can be bought at any Repco or BNT as here in NZ, these pumps send fuel to a Separate Tank which has a -12an return back to tank (this may need a restrictor to give a small amount of pressure) the tank has the Bypass return from Regulator, just below the return to tank. At the bottom of the tank is a -10an supply line to my Aeromotive 150gph street pump, that has a -8an line to the regulator etc, I believe this is adequate to supply the 675bhp engine.

Regarding hot fuel being returned from the Regulator I dont think that is an issue as it is being cooled by the flow from the tank and back to the tank, I think the trick is not to circulate the fuel to much but obviously a bit more than the carb needs.

Nice plumbing job Aussie Mike!
