    Full StarFull StarFull StarFull StarFull StarSimple and accurate catalog, first time user success!
    by Kenneth from Bloomington, Minnesota on September 13, 2015
    My 1980 I/O needed a fuel pump. After visiting many local sources I viewed the iboats catalog, found what I needed, saved a hundred dollars and received exactly what I needed 3 days later. Thanks iboat!

    Q:
    What is the output pressure on this pumpkin?
    A:
    Sierra confirms it is 5-8 PSI.
    Q:
    My cross reference for 1989 omc 3.0L cobra is 985337. Will this pump fit, and is a spacer needed along with a gasket?
    A:
    Unfortunately, Sierra does not make a replacement for that fuel pump. You may contact OMC for the parts needed.
