    Alternative fuel pump rather than replace the whole assembly? M73

    Hi Guys

    Whats an alternative fuel pump to replace mine rather than replace the whole assembly?

    Iv read the sticky but thats for the dual pump M70 and S70, I have the single pump M73 and im trying to avoid to fork out $500+ on the whole assembly

    Thanks

    This is probably not the solution you are looking for but maybe this info is helpful. I bought my 91 850i with what I was told was a Ford Mustang (aftermarket?) single Fuel Pump mounted externally beside the fuel filters. Original pumps were both removed. I always felt nervous and hope to one day put it back to original but to be honest, I've run it this way for over 6 years/ 50k kilometers without the slightest problem. I can't give you many details on how it is hooked up other than to say power comes off only 1 of the pump's wiring at the tank. The fuel pump's outlet goes into a t and then to the 2 original fuel lines up to the 2 fuel injector rails.

    I believe the part number for just the pump would be 16 14 6 768 653 but you should double check with realoem.com by entering your last 7 of the vin.
    Many sources sell the oem pump for a reasonable price, or you can get an aftermarket one.

    Thats the 1st thing I read! Unfortunately, mine is a single pump design. According to my research, Bosch 69493 should do the trick
