  • fuel pump orientation

    Howdy,

    Does a fuel pump really care if its verticle or horizontal? Thinking of how to convert a TBI fuel system into an MPFI system by using the stock TBI pump as a lift pump to fill something like a a 5in diameter by 18in pipe with a 454SS fuel pump mounted lengthwise in the tube under a baffle and an overflow off of the back end of the tube at the highest point. I know these pumps are normally mounted vertically so will it care if it's laid over onto its side?

    Thanks,

    Interesting idea. Would the 'lift' pump be operating full time with the 5 x 18 tank remaining full with a return line for the lift pump and the EFI SS 454 pump dead head to the fule rails?, or does that have a return too?

    Obviously I'm not too familiar with production EFI hardware.

      My idea would be for both the overflow and bypass to go back into the tank though I don't know enough about a TBI pump to know if it'd run in a deadhead configuration into the surge tank. Heck I could be completely overworking this and I could just put the 454SS pump into the hanger for the TBI tank. Worse comes to worse, this would work with the in tank pump for the carborated 69-70 Riviera's.
