2001-2005 Duramax Twin CP3 Controller (WCF100093)

Controller and harness to run a second CP3 injection pump on a 2001-2005 LB7 or LLY Duramax. When one pump cannot keep rail pressure up with big injectors and tuning, a twin CP3 setup is the fix, and this controller is what makes the second pump behave like part of the factory fuel system.

The kit includes the controller, wire harness and connectors. It is intended for use with a Wehrli or similar dual CP3 kit and requires tuning to take advantage of the added fuel volume.
