    Default Fuel pump on a Mercury V6

    Anyone ever use the Mr. gasket co. Micro Electric fuel pump on a Mercury carb motor? They have two 2-4PSI and 4-7 PSI.

    Mr. Gasket pumps from the auto parts stores are POS , I went thru 3 on my jeep in a matter of weeks. Go with Carter , Holley , or Weldon for something that will last

    Default pumps

    you want to stay away from pulse pumps
    not enough volume as fred indicated

    blade slingers work the best for low pressure and high volume
    mercury uses the holley red pump for hp carb motors
    this pump is good up to 8,000 rpm
    after that,,, motor needs more volume
    the weldon is the pump of choice that racers use for high output volume
    with a cosistant pressure
    most high volume pumps fluxuate the pressure too much as the regulator
    opens and closes,,,,weldon has a more steady low pressure adjustment
    also they are made for aviation and marine applications
    so last longer than automotive pumps

    I always found the holly's problematic the magnets seemed to come loose off the body. The Weldons are horrendously expensive. I now use Carters the oldest of which is 4 years old.
