Test the Fuel Select Operation -
Ford 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 when 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.
Perform this test after checking
the gasoline and LPG fuel levels,
and warming the engine to normal
operating temperature.
1 At the platform controls, move the fuel select
switch to gasoline and then move the engine
idle control switch to foot switch activated high
idle (rabbit and foot switch symbol).

allow it to run at low idle.
