It is the only in-tank lift pump that is capable of handling up to 800HP. With your factory lift pump, there is an issue with fuel delivery because the CP4 vacuum is the in charge of drawing fuel, which puts additional stress on the injection pump and lead to premature failure. These issues will be solved with the help of two OEM quality gerotor pumps that will increase flow capacity and make the lift pump more reliable. When it comes to integrating this lift pump into your build, the process is made simple by being able to eliminate the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank issues that occur when seeking a higher flow lift pump to meet your engine's need.
