Shep69 I have a Spectra premium fuel tank with the pump in the tank that has 2 fittings on the sender where the pump is mounted to be able to run a feed & return line. I have not yet decided if I am going to use a carb or go EFI. I am using for the fuel line ni copp (nickel/copper) line that is easy to form & bend & use where the line connects at the fuel tank, fuel filter, & at the engine Gates barricade fuel injection hose. I am using Aeroquip socket less hose ends for the connections from the hard to the soft lines, & a Quick Fuel fuel pressure regulator if I run a carb.
