Fuel System Components

The LML fuel system category is broader than the CP3 conversion page. It covers stock repairs too, including injectors, pressure regulators, fuel lines, rails, CP4 parts, filters, and related hardware.

Repair and upgrade parts include injectors, pressure regulators, fuel lines, rails, CP4 components, filters, and related hardware for 2011-2016 GM Duramax trucks. If the truck has fuel contamination, plan the repair around the whole system, not just the pump.
