2.9 Fuel System Maintenance

WARNING
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
The fuel system. Explosive fuel vapors can cause severe
injury or death. Vaporized fuels are highly explosive. Use
extreme care when handling and storing fuels. Store fuels in a
well-ventilated area away from spark-producing equipment
and out of the reach of children. Never add fuel to the tank
while the engine is running because spilled fuel may ignite on
contact with hot parts or from sparks. Do not smoke or permit
flames or sparks to occur near sources of spilled fuel or fuel
vapors. Keep the fuel lines and connections tight and in good
condition. Do not replace flexible fuel lines with rigid lines. Use
flexible sections to avoid fuel line breakage caused by
vibration. Do not operate the generator set in the presence of
fuel leaks, fuel accumulation, or sparks. Repair fuel systems
before resuming generator set operation.
Gas fuel leaks. Explosive fuel vapors can cause severe
injury or death. Fuel leakage can cause an explosion. Check
the LPG vapor or natural gas fuel system for leakage by using
a soap and water solution with the fuel system test pressurized
to 6--8 ounces per square inch (10--14 inches water column).
Do not use a soap solution containing either ammonia or
chlorine because both prevent bubble formation. A successful
test depends on the ability of the solution to bubble.
Routine service items include draining water/sediment
from piping at petcock or pipe end cap, checking for fuel
leakage at pipe connections, checking flexible sections
for cracking or chafing, and keeping components clean
including fuel regulator vent holes.
A grease or wax residue tends to accumulate in the
piping and fuel regulators over time. If fuel system
problems persist, disassemble the fuel system
components and check for residue buildup. Remove
any residue with a brush and mild detergent.

2.10 Fuel Regulator Vent Tubes

Models 20RESA(L) and 20RESC(L) may be equipped
with the fuel regulator vent tubes shown in Figure 2-19.
If the generator is equipped with the regulator vent
tubes, check that the tubes are not blocked. Clean out
the tubes, if necessary.
1. Regulator vent tubes, qty. 2
2. Check for debris. Clean out the tubes, if necessary.
