6.1.7 Low Fuel (Level/Pressure) Switch
Some gas-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 6-15, Figure 6-16,
and Figure 6-17.
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.
