Systems are disclosed for supplying fuel to fuel-injected gensets in a recreational vehicle. An apparatus includes a fuel injection system having a fuel reservoir and a first pump fluidly coupled to the first reservoir and structured to supply fuel to the fuel reservoir. The fuel injection system is further provided with a pressure sensor and a second pump. The second pump is fluidly coupled to the pressure sensor and structured to provide pressurized fuel from the fuel reservoir to one or more fuel injectors of an associated engine. The second pump is a variable speed fuel pump.

Throttle body

A system is disclosed including a primary engine that provides vehicle propulsion and a secondary engine that drives a generator to provide auxiliary power. The system further includes a first exhaust gas passageway from the primary engine and a second exhaust gas passageway from the secondary engine. The system further includes an emission treatment device including an exhaust inlet to treat exhaust from the primary and secondary engines. The system further includes an exhaust routing device that selectively routes exhaust from the first passageway or the second passageway to the exhaust inlet. The exhaust routing device at least partially blocks the first passageway or the second passageway from fluid communication with the exhaust inlet.
