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 76, Figure 77, and Figure 78.
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.
