    since the CD has no bypass covers you must get a pulse from the crankcase to run a fuel pump  by modifying the  air nipple feeding air to the tank.

    it involves removing a small rubber check valve,   blocking a air channel, finding.. and  installing a  single  line (modern) side connector… and a fuel pump of course…….. actually not all that difficult to do…great project

     

    I learneda lot from this book which covers maintenance , fuel pump conversion carb upkeep etc… quite detailled asa learning book … and the 5.5hp is covered

    Cheap Outboards: The Beginner’s Guide to Making an Old Motor Run Forever: Wawrzyniak, Max: 9781891369629: Books – Amazon.ca

    the alternative is to locate a  good… spare dual hose  tank . they are out there but….pricy .

    see video   pics are a 7.5hp
