If the unit shows signs of overheating, you will need to enlarge the air openings.

  • Page 29: Fuel Tank

    If the generator is to share the vehicle engine's tank, separate fuel pickup tubes are required for the engine and the generator. Generac recommends that you make the fuel pickup tube 2 to 3 inches (51 to 76 mm) shorter than the vehicle engine's pickup tube.
