When i built my F.I. StangII i used a Ranger truck inline pump.i had a holley blue pump to pull fuel out of the tank, and feed a 1gallon surge tank. The Ranger pump pulled fuel out of that to feed the engine. This setup never starved a mildly built 5.0 Everything was steel lines, and flare fittings up to the enginewher i had one piece of high pressure rubber to connect to the fuel rail.
