Moroso's External Oil Pump System has shown significant horsepower increases when used in conjunction with our External Wet Sump Oil Pans. Mounting an oil pump outside the engine (similar to a dry sump setup), allows the use of a full-length windage tray for less windage and more power! An External Oil Pump also eliminates torsional stress on the camshaft, as well as spark scatter and resultant horsepower loss caused by an internal pump.
Same rotor and scroll (Gerotor) design as our famous 3, 4, 4-1/2, and 5-Stage Dry Sump Pumps
Includes .875" or 1.100" wide pressure sections depending on application
External pressure adjustment allows a +30 or -30 psi range from factory setting of 60 psi
