Moroso GM LS Dry Sump Oil Pumps

These oil pumps have a bracket on them that bolts to the factory A/C bracket holes on the right side of a GM LS engine block.

Moroso has introduced two new Part Nos. 22303 – a Dry Sump Pump Three Stage, Right Side GM LS Bracket, 1.200 Pressure/1.700 Scavenge and 22304 – a Dry Sump Pump Four Stage, Right Side GM LS Bracket, 1.200 Pressure/1.700 Scavenge.

Part No. 22303

These oil pumps have a bracket on them that bolts to the factory A/C bracket holes on the right side of a GM LS engine block. Tri-lobe aluminum scavenge sections featuring individual timing gears ensure proper clearance at the highest RPMs. The spur gear pressure sections are based off Moroso’s billet wet sump pump design, which have thousands of race wins under their belt.

Part No. 22304

These pumps also have variable spring rates that optimize the oil pressure for smooth, reliable oil pressure readings. Multiple #16 scavenge outlet options for increased flow back to your dry sump tank and/or fitment requirement on your application, includes all necessary fittings. Moroso Tri-Lobe dry sump oil pumps weigh almost half of gerotor pumps and take up to 40% less power to drive. Must be used with ATI hub with integral HTD pulley.
