Engine Fuel Connections
Identification tags are attached to the fuel supply line and fuel return line
connections. All models require a fuel return line from the injectors to the tank.

restriction limitations of the fuel pump.
Install a fuel tank that has sufficient capacity to supply the generator set operating
continuously at full rated load for the planned period of operation or power outage.
