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.

Draining the fuel system. Explosive fuel vapors can cause severe injury or death. Spilled fuel can cause an explosion. Use a container to catch fuel when draining the fuel system. Wipe up spilled fuel after draining the system.

5.1 Gasoline

Fuel system design. Design the generator set gasoline fuel system to operate independently of the vehicle engine fuel system if the operator may operate both engines simultaneously. Kohler Co. recommends using separate fuel tanks, if possible; however, using separate fuel tanks is usually impractical because of space restrictions. In most installations, both engines operate off a common tank with a separate dip-tube arrangement as shown in Figure 5-1. The dip-tube arrangement prevents the larger engine from starving the smaller engine of fuel. The generator set dip tube is generally shorter than the vehicle dip tube to stop the generator set before the vehicle engine runs out of fuel. With the dip-tube arrangement, the generator may not get fuel during a low fuel-supply situation.

Tee arrangement. Do not use the tee arrangement. Do not tee into the fuel-supply or -return line of fuel-injected systems.

Note: Supply the fuel using a two dip-tube arrangement if the generator shares the vehicle engine fuel tank. Consult an authorized Kohler service distributor/dealer for further fuel system installation information.
