Cummins Power Generation A058V085 Details and Specifications
P9500df High Altitude Regulator Kit
The high altitude regulator kit includes regulator jets for operation at altitudes above 2000 feet above sea level. The high altitude Regulator jets fit the 420cc P9500df gasoline/LP Propane engine.
*This kit only fits Cummins P9500df Generators Built On/before July 19, 2020.
*For Cummins P9500df Generators Built After July 19, 2020, Use Part A065P9007
Gasoline: Use the corresponding Carburetor Jets A058V084 (sold separately) above 2000 Feet.
As altitude increases, the amount of oxygen in the atmosphere decreases by approximately 3 percent for every 1000 feet in elevation. The factory installed regulator jets perform best at altitudes below 2000 feet. Above 2000 feet, the fuel-to-air mixture becomes too rich. High altitude jets provide the right mixture of propane and air.
The 420cc high altitude regulator kit for the P9500df includes four jets.

Every 1000 feet in altitude decreases available power by approximately 3 percent because of the corresponding decrease in atmospheric oxygen. Use of the correct high altitude jets above 2000 feet will reduce fuel consumption and emissions compared to factory jets, but does not improve power output.
**Important Operation Note: Use of a high altitude jet below 2000 feet may damage the generator engine if operated under load or for more than a few minutes.
