Ok I guess I should clarify that I am running a mechanical fuel pump and don't intend to change that anytime soon.

The only rubber fuel line I have left is the 4" run from the hard line to the fuel pump inlet which I do need to change out. From the fuel pump outlet to the carb is all PTFE line. The fuel filter is right before the carb.

Gas tank is brand new as is sending unit. The little rubber hose from the fuel sender to the hard line is new and a piece of hose that is supposedly specially ethanol safe.

The hard line is stainless steel.

So with that in mind, what is a good mechanical pump to run for my setup?
