Adding a lift pump on your 11-14 Duramax is arguably the single best modification you can make. These trucks did not come with a lift pump from the factory which means the injection pump (CP4) must pull the fuel from the tank, through the filter, then pressurize it for the injectors. A lift pump will alleviate the CP4 from having double duty, and make its only duty to pressurize the fuel for the injectors. Proper pressure and volume, provide a noticeable bump in drivability and performance. 

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!
