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 with full pop off at 55-60 psi. 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 2.250in. Chrome Moly gerotor gears. 20% more pressure and 20% more scavenge volume over stock. Magnet to help protect gears and pressure relief valve. Billet 7075 aluminum construction with red anodize, 7075 material holds tighter tolerance under temperature. Increased scavenge port holes and galleys requiring them to be matched up to a Feuling High Flow camplate. Increases oil pressure. Increased kidney passage volume. Eliminates blowby and wet sumping. Cooler oil and engine temperatures. More horsepower and torque to the rear wheel. Made in the u. s. a. NOTE: Must be matched to a Feuling High Flow camplate.
