Fuel System Components

The LBZ fuel system category is where injectors, injector nozzles, CP3 pumps, nozzles, regulators, fuel lines, and related repair & replacement components come together. LBZ owners often shop injectors and injector nozzles when the truck starts hazing, knocking, or losing clean fuel delivery.

LBZ injectors, injector nozzles, CP3 pumps, fuel pressure regulators, rails, lines, and supporting parts all play into fuel system repairs on 2006-2007 6.6L GM Duramax trucks. If injectors are coming out, inspect the seals and high-pressure parts while the job is open and common failure spots are easily accessable.
