    Dual fuel pump upgrade

    I've been having problems with the engine cutting out a second after a fast right hand turn. The car exhibited the same problem with my M50 and now with the S52, while the tank was relatively full. I have an audi surge tank I want to run and I want to upgrade the fuel pumps (for some reason a PO converted my 91 into a dual pump setup). Can I run the stock early car lifter pump with something like a Bosch 044 or will the mismatch in pumping rate cause problems? Any other options for a better pre-pump?

    yes it will work fine. the bigger external pump will actually make life easier for the internal pump.
