Component Description
Secondary
Regulator
Located near the generator set, the secondary regulator reduces the
higher line pressure to a working pressure of 6 - 12 inch water column
(1.5 - 3.0 kPa). Higher pressure before the secondary regulator is
necessary to ensure that there is enough fuel available at the secondary
regulator for a fully loaded generator set.
Fuel Line Connects to the fuel supply. It must be sized properly using the propane
fuel line sizing charts (see the Fuel Line Selection appendix).
Installation must comply with all national, state, and local codes.
Cummins Flexible
Fuel Line
Protects the fuel system from vibration, expansion, and contraction.

WARNING
Propane presents the hazard of fire or explosion that can cause severe
personal injury or death. Do not permit any flame, spark, arc-producing
equipment, switch, pilot light, cigarette, or other ignition source near
the fuel system. Keep an ABC type fire extinguisher nearby.
