I've been looking at the Aeromotive A1000 fuel pressure regulator. It says you can still use an efi pump and lines when you covert from efi to carb. How much HP can the stock lines support running to a carb?
well they say that on efi the stock pump is good for 400hp. i have never heard of anyone upgrading there fuel lines (at least that upgrade never seems to be in peeps sig). i ripped out my injected fuel lines and went with a low psi high volume pump and 3/8 fuel lines in my car.
