slow down ......... dont scrap that tank yett ...... you can run that tank with the in tank pump. all you have to do is wire the in tank pump to a switched hott (wire is hot with the key on) and install a adjustable fuel pressure regulator in the fuel line before your carb(preferabily under hood near the fender well) be sure the regulator has a return line and route that return line back to the tank .. the tank will have a fitting for it. set the regulator for about 7pounds of pressuer, and your in business. never never never run an eletric fuel pump before your mechanical pump..... first off you will be pushing fuel tru your mechanical pump and it will impeed flow and if the diafram in the mechanical pump ruptures of leaks (and is likely to do with that much pressuer you will be pumping fuel into your oil and it will automaticaly wash all your engine berrings and internal components. now before you say hey a clean engine is a happy engine, there goes all the lubrication of your engine and you will glaze your cylinder walls, eat up your berrings score your crank and destroy your cam. so i say pitch your mechanical pump, put a block off plate over the hole,and follow my directions on a regulator and live happly ever after.......... a side note your mechanical pump will have a hard time pulling fuel tru that eletric pump if you plan on going the other way .......... oh and a side note if you like you can run the power supply tru a oil pressure sending unit (one desinged to do this) and should your oil pressure fall below a safe level it will shut off the fuel to your engine, or if your into radical wheeling you can get a sensor that will kill your fuel in case of a roll over both of which will save your engine and reduce the risk of a fire.......... you can do that with a mechanical pump!
