Feuling HP+ Oil Pump For Harley Davidson Oil Cooled M8

  • Precision-machined pressure relief valve and bore
  • Every pump is bench tested, the relief valve is seated and sealed to a minimum of 30 psi (EU: 2,06 bar) with full pop-off at 55-60 psi (EU: 3,79 bar - 4,13 bar)
  • 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
  • Eliminate common pressure and scavenge issues associated with the factory oil pumps
  • When matched to a Feuling camplate, pumps reduce engine and oil temperatures, increase oil pressure volume, and scavenge volume on the return side to reduce build up of oil in the crankcase
  • Increase oil flow in and out of the engine with corrected tolerances, oil passages and larger geroter gears
  • High-flow 2.250" (EU: 5,72 cm) Chrome Moly gerotor gears
  • 20% more pressure and 20% more scavenge volume over stock
  • Magnet to help protect gears and pressure relief valve
  • Billet 6061 aluminum with natural finish
  • Increased and optimized scavenge port holes and galleys (requires being matched to a Feuling High Flow camplate
  • Increases oil pressure
  • Increased kidney passage volume
  • Eliminates blow by and wet sumping
  • Cooler oil & engine temperatures
  • More horsepower and torque to the rear wheel
  • HP+ and RACE SERIES oil pumps MUST be matched up to a FEULING HIGH FLOW camplate
  • Made in the U.S.A.

NOTE: Use of Gear Drive camshafts require block off plates - see #8016

Due to the mass call volume & inquires with requests for the M-Eight oil pump back cover O-ring/seal groove, weve added the groove! (5/11/21). Although Feulings in house testing on healthy engines did not show a benefit. The O-ring may have potential benefits in certain circumstances such as engines with higher cylinder leak down, poor subseal O-ring seal, raised sump hole & or sump plug (see M8 PRO TIP below) & looser lifter to lifter bore clearances.
