Fleece Performance LML CP3 Conversion Kits
Why convert your LML's fuel system from a CP4 to a CP3? Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms—resulting in costly repairs for owners when a CP4 fails. You can improve your LML Duramax's reliability and fueling capability, as well as avoid costly failure with Fleece Performance LML CP3 conversion kits. They provide OEM fit-and-finish features, like Fleece's exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and their valley feed line to support aftermarket lift pump applications. Fleece Performance LML CP3 conversion kits are offered with or without pump and the pump kits come in two different style pumps—a Bosch CP3 injection pump or Bosch CP3 pump with heavy-duty 10mm cam. Choose the kit that is right for you. All kits include: * CP3 to rail high pressure fuel line * High-flow CP3 feed and return fuel fittings * Preformed fuel feed and return fuel hoses * CP3 mounting adapter * Dosing injector distribution block, feed and return lines * FCA extension harness * Low pressure fuel feed line * Hardware kit
