    Mercruiser 3.0 Fuel Issues

    Need clarification There needs to be a tube that goes down to the bottom of the fuel tank. If the fitting is removed and there is no tube, then check the tube is not part of the tank. If there is no tube which goes to the bottom of the tank then that is a problem Antisiphon valve

    Mercruiser 3.0 Fuel Issues

    Good deal If you have a regular marine fuel pump which is motor driven off the side of the block, would like to know which one.

    If the smug mark by the pin is zero, and the intake valve had closed prior to bringing it around the last 180* then looks great

    Old ford 302 no spark

    Where the rotor is pointing is not that much of an issue, so long as the firing order is correct. It pointing 180* out (or backwards) just means instead of it being on #1 compression, its on #1 exhaust stroke

    2002 Mercruiser 4.3L MPI Fuel Pump Style

    The 0M number is the serial number, and your correct 861156A1 is the pump part number. Just search on it and it will show several that will work The pump can pressurize more then 42psi but the regulator (item 13) which is attached to the cooler keeps the pressure constant. The noise might be...

    It should be dead on it. When a timing light is used, the pointer aligns up with the additional marks on the balancer. There are other marks with numbers. Your looking for 6 or 8* BTDC when running
