  • Installing Mechanical fuel pump Mercruiser 470

    I installed a replacement mechanical pump because the old one was leaking at the diaphram. Now I am getting no fuel to the carb and I'm curious what I could have done wrong? It seemed simple enough to replace. Do I need to prime the pump somehow?

    A little help please.

    What type of engine are you attempting to get running?
    From Mercruiser:
    Anyone who uses a service procedure and/or tool, which is not recommended by the manufacturer, first must completely satisfy himself that neither his nor the products safety will be endangered by the service procedure selected.
