Kohler 20-3250 kW manual Low Fuel Level/Pressure Switch, Prime Power Switch Kit

6.1.7Low Fuel (Level/Pressure) Switch

Some gaseous-fueled models offer a low fuel pressure switch. The low fuel pressure switch connects to the same terminal as the low fuel level switch on diesel- or

gasoline-fueled models. See Figure 6-10 and Figure 6-11. See Section 6.2, Accessory Connections, for terminal identification.

Note: The main tank or the transfer/day tank includes the low fuel level switch. The fuel tank supplier typically provides the low fuel level switch.
