I am currently running a shitty, early model EFI on my 460 that clearly doesn't work. Swapping to a carb. Thinking about the larger CFM Holley Truck Avenger. Question is: what do I need to run between the pump and carb and should I run

Electrick Fuel Pump - Stock Fuel Pump - Carb

or

Electric Fuel Pump - Regulator - Carb

and what pressure should I set the regulator at?

i'm running electric fuel pump on my q-jet, i just went to the parts house and found one that has he same pressure and gph as the stock one, no regulator, just straight to the carb

I would run stock electric pump to regulator to carb. The pressure should be set at 9 to 15 pounds.

If ya run like a Holley blue, with a regulator and run about 7 psi you'll be just fine.........more than 7 psi and your prone to blow blow the seats out...........
