    I've got a ground wire that is tagged FUEL ,does this power the VRO ? Is the fuel pump itself mechanical? Thanks

    There is an electrical connection to the fuel-oil pump.


    I've never worked on a 2004 Johnson, so I don't know how the pump is driven.
    Older models were driven by pressure changes from the crankcase.
