Test the Fuel Select Operation -
Gasoline/LPG Models
The ability to select and switch between
gasoline and LPG fuels as needed is essential to
safe machine operation. A fuel selection can be
made whether the engine is running or not.
Switching malfunctions and/or the failure of the
engine to start and run properly in both fuel
modes and through all idle speeds can indicate
fuel system problems that could develop into a
hazardous situation.
Note: Perform this test after checking the gasoline
and LPG fuel levels, and warming the engine to
normal operating temperature.
