3.6 Fuel System
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
WARNING
A fuel solenoid valve turns the fuel supply to the fuel
pressure regulator on and off.
The regulator then
reduces fuel pressure for delivery to the fuel metering
(fuel mixture adjustment) valve. The fuel flows from the
metering valve to the carburetor in a gaseous state. The
carburetor mixes the fuel with intake air for consumption
by the engine.
Two fuel metering valves allow field-conversion
between natural gas and LP vapor. The fuel metering
valves are factory-sealed to comply with applicable
emission standards and to provide the best possible hot
and cold starting. Do not adjust the fuel metering valves.
Have the fuel conversion procedure performed by
trained and qualified personnel.
