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

Fleece Performance CP3K fuel pump kits are a valuable lesson in supply and demand. Simply put; your diesel engine's demand for more fuel cannot be supplied by your stock CP3 pump, thus its' time for a new supplier--CP3K. These modified pumps are engineered to eliminate the factory fuel flow restriction that usually begins at 3,000 rpm. Your stock pump at this point starts losing fuel flow and rail pressure, which equates to loss of horsepower when you need it most. Reverse the trend; maintain the desired fuel rail pressure through your entire rpm range with cost-effective Fleece CP3K fuel pumps.

These kits replace the factory fuel filter housing with a new filter base, integral high-flow fuel heater, Water-In-Fuel (WIF) sensor, and Donaldson spin-on canister style filter. The filter base eliminates the factory fuel primer bulb and is intended for use with a positive pressure lift pump, such as Fleece's PowerFlo lift pump or alternative frame mounted pump. Kit includes: * Fuel filter base with integral fuel heater and fittings * Donaldson 3 micron fuel filter and water separator * Pre-formed hose and hose clamps * Wiring harness and fuse taps * Water-In-Fuel (WIF) sensor and adaptation harness

Some L5P 6.6L Duramax vehicles have a secondary MAP sensor. The problem: Its direct placement into the intake air stream from the factory causes the soot buildup to become an ongoing maintenance problem, requiring routine cleaning or replacement of the sensor. The solution: Fleece Performance secondary MAP sensor spacers. They move the sensor from the direct intake air stream to reduce soot buildup over time and eliminate the need to routinely clean or replace the sensor. Each kit includes mounting block (spacer), fastener, and O-ring.
