Simple solution- - - -Install an electric pump back near the fuel tank, and use a discarded fuel pump housing less the internal parts bolted to the engine with a blind gasket under it to route the fuel lines through for a stock appearance. Just install an oil pressure switch inline with the pump power to be sure the pump shuts off if the engine stalls. I can draw up the pump power circuit I used pretty often for this application if you like- - - -it involves using a pressure switch and a bypass circuit to run the fuel pump during cranking before the oil pressure builds up. Good luck!
