2022+ RZR Pro R 4 Cylinder Fuel Pump Assembly with High Flow Pump

Fits 2022+ RZR Pro R 4 Cylinder models Complete pump assembly is ready to drop in the tank Extremely high quality fuel pump is compatible with ethanol mixed fuels up to E-85.  The OEM pump does okay with E85, but it's life is limited. High pressure for big fuel demand with our 255 liter per hour pump is perfect for stock vehicles, and a must have for those running forced induction systems The OEM and our pump are pressure regulated with an internal housing regulator.  Our pump has the correct and high quality regulator for the Pro R 4 cylinder. Great replacement if you think/know your factory pump is weak or if your current pump is not working Weak fuel pumps normally show a loss of power/peak RPM at wide open throttle.  As they worsen, you may have low and mid range stumbling as well.  Keep in mind sometimes bad fuel pumps send or allow debris to reach the fuel injector inlet screen and the injectors may also need cleaning or replacing. Pump housing is assembled at the AA facility in
