My Onan is starved for fuel

    Does anyone know if Onan generators (2.8 Microlite) have fuel pumps ?
    Mine will start right up if it sits for a while but dies shortly thereafter.
    I pull the fuel line at the carb and it's dry as thought the unit is not pulling fuel from the tank.
    It's tapped into the main vehicle tank.

    How much fuel is in your tank? They will not pull fuel at less than 1/4 tank.

    The problem is consistent, even with a full main tank.

    My propane OnonEmerald 4000 did the same thing when the connections to the battery were loose. don't know why, but it did.

    Parts of the line were cracked.
    I replaced what I could get to but that leaves some parts I couldn't reach going up behind the main tank.
    So what next ?
