FUEL SYSTEM -- LPG
LPG FUEL SYSTEM
The liquid withdrawal LPG fuel system is made up
of five components which are: the LPG fuel tank,
pressure relief valve, fuel filter lock,
vaporizer-regulator, and the carburetor.
Liquid LPG fuel flows from the LPG tank, under its
own pressure, to the pressure relief valve. This
valve is normally closed, preventing LPG fuel from
escaping into the atmosphere. The valve opens to
relieve pressure if the fuel pressure exceeds
system limits. From the pressure relief valve, the
liquid LPG fuel is piped to the fuel filter lock. The
fuel filter lock filters unwanted tank scale and
deposits out of the LPG fuel. The fuel filter lock
also stops the flow of LPG fuel when the engine is
not operating. The oil pressure switch controls the
fuel filter lock. When the engine oil pressure is
4 psi (30 kPa) or greater, the oil pressure switch
permits an electrical current to open the fuel filter
lock which allows LPG fuel to flow on to the
vaporizer-regulator. The oil pressure switch is
bypassed when the engine is being started,
allowing LPG fuel to flow.
The vaporizer section of the vaporizer-regulator
converts the liquid LPG fuel into a gaseous LPG
fuel. From the vaporizer section, the gaseous
LPG fuel is sent to the primary regulator section
of the vaporizer-regulator. The primary regulator
section reduces the pressure of the LPG fuel. The
secondary regulator section reduces the LPG fuel
pressure to the level required by the carburetor.
From the vaporizer-regulator, the LPG fuel is sent
to the carburetor where it is finally metered into
the air flow which is sent to the engine
combustion chamber.
IN--LINE FUEL FILTER --GM ENGINES (For
machines serial number 001424 and above)
The in--line fuel filter is located between the
lock--off solenoid and the fuel line leading to the
vaporizer--regulator. Replace the fuel filter every
400 hours of operation.
