Low Fuel (Level/Pressure) Switch
Some gaseous-fueled models offer a low fuel pressure switch. The low fuel pressure switch connects to the same controller
terminal as the low fuel level switch on diesel-fueled models. See Figure 73, Figure 74, and Figure 75.
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.
