Performance Replacement Lift Pumps for GM Duramax Diesel Trucks.
Raptor RP-150 GPH R2SBC137 2011-2014 GM Duramax
The Raptor® Lift Pumps allow more fuel to flow than a stock pump. If you have an upgraded engine with larger injectors, etc., then the Raptor® Lift Pump can improve fuel flow for improved performance. A large engine can starve for fuel if a better, high rate flow pump is not used!
