WARNING

Explosive fuel vapors.

Can cause severe injury or death.

Use extreme care when handling, storing, and using fuels.

Explosive fuel vapors can cause severe injury or

death. All fuels are highly explosive in a vapor state. Use extreme care when handling, storing, and using fuels. Store fuel 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 since spilled fuel may ignite on contact with hot parts or from ignition spark. Do not smoke or permit flame or spark to occur near potential sources of spilled fuel or fuel vapors. Keep fuel lines and connections tight and in good condition— don’t replace flexible fuel lines with rigid lines. Flexible sections are used to avoid breakage due to vibration. Should any fuel leakage, fuel accumulation, or electrical sparks be noted, DO NOT OPERATE GENERATOR SET. Have systems repaired before resuming generator operation.

Gasoline— Store gasoline only in approved red containers clearly marked GASOLINE. Do not store gasoline in any occupied building.

The electric fuel pump includes a screen. (See Figure 3-7.) At the recommended interval or when clogging is suspected, inspect and clean the screen as follows:

1.Shut off fuel flow to electric fuel pump at tank or at in-line shutoff valve. Disconnect harness plug (see Figure 3-7 for location).

2.Disconnect fuel lines from electric fuel pump, draining fuel from the lines and pump into a suitable container to prevent spillage into the bilge.

3.Remove the three nuts that secure the electric fuel pump to the mounting bracket.

4.Remove the three mounting studs from the electric fuel pump.

5.Remove the cover plate and inspect the screen. Remove any debris or residue. Be sure the screen is intact. If the screen is damaged, replace the fuel pump.

6.Check the O-ring seal. Replace the O-ring if it is nicked or eroded.

7.Reinstall the cover plate and secure it to the fuel pump by reinstalling the three mounting studs.

8.Insert the three mounting studs on the fuel pump through the mating holes in the mounting bracket. Reinstall the three nuts to secure the fuel pump in place.

9.Reconnect the fuel lines to the fuel pump.

10.Open fuel line at tank or in-line shutoff valve and check for leaks from the fuel pump at fuel line connections and cover plate.
