Feuling Race Oil Pump for 17-Up Harley-Davidson Milwaukee Eight Engines

FEULING OIL COOLED [SKU # 7020] and WATER COOLED [SKU # 7021] high volume billet oil pumps are a must have for the Milwaukee Eight engine that you want to last. The increased oil volume from the larger gears and properly sized passages along with the pressure relief valve seat and seal from these oil pumps is essential for proper oiling system function. The FEULING oil pumps eliminate common pressure and scavenge issues associated with the factory oiling system.

These oil pumps have a precision machined pressure relief valve and bore. Each oil pump is bench tested, the relief valve is seated and sealed to a minimum of 30 psi with full pop off at 55-60 psi.

The FEULING oil pumps require use of the FEULING HIGHFLOW camplate, the combo increases oil flow in and out of the engine with corrected tolerances, oil passages and larger geroter gears. Reduces engine and oil temperatures, increase oil pressure volume and scavenge volume on the return side to reduce build up of oil in the crankcase.

FEULING offers the HP+ and RACE SERIES oil pump options to suit your oil or water cooled engine build and budget needs.
