  • NG priming for easy engine start when on Natural Gas.
  • Control of the NG fuel flow, cuts the power off when the engine stops or is arrested.
  • Display of the natural gas tank remaining fuel fraction on 5 LED stand-alone panel
  • Automatic Fuel Selection Mode. (on Fuel Injected Engines only)
    • Start on gasoline, switch to NG while starting.
    • Switch to gasoline when NG fuel is depleted to the minimum set pressure, adjustable.
  • NG fuel selection starting and running on Natural Gas only.
Selex™ fuel mode selection is controlled / switched from a double pole double throw switch. Selex™ is universal, therefore, the minimum NG fuel switching point must be set for each vehicle.
