Convert your LML's fuel system from a CP4 to a CP3
Improve your LML Duramax's reliability and fueling capability with a CP3 conversion. Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms. Failures of the CP4 are extremely costly and require replacement of the entire fuel system. Avoid a costly failure down the road and convert your CP4 to a CP3 on the 2011-2016 LML Duramax platform. Our LML CP3 converstion kit provides you with OEM fit-and-finish features like our Fleece Performance exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and our valley feed line to support aftermarket lift pump applications. This kit does not include a CP3 injection pump.

What LML CP3 Conversion Kit is right for you?
We've got a number of choices when it comes to CP3 conversion kits, let us help you in the proper selection:
FPE-LML-CP3-NP: Our "No Pump" kit for the LML CP3 conversion gives you the option to select your own CP3 pump for your application. Our kit provides you with all of the hardware you need to adapt a LBZ/LMM based Bosch CP3 to your 2011-2016 LML Duramax.
FPE-LML-CP3-WP: Our "With Pump" kit for the LML CP3 conversion gives you a brand new LBZ/LMM Bosch CP3 along with all of the hardware you need to convert your CP4 equipped Duramax to a CP3. This kit is designed for use with or without a low pressure lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 11 psi when utilizing this kit.
FPE-LML-CP3-10: Our Heavy Duty kit for the LML CP3 conversion features a brand new LBZ/LMM Bosch CP3 equipped with a Fleece Performance 10mm stroker cam along with all of the hardware you need to convert your CP4 equipped Duramax to a CP3. This kit is designed for use with or without a low pressure lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 2 psi. Engine surging may be induced by the additional fuel pressure of a lift pump operating at pressures over 2 psi. If you are intending to combine this kit with a Fleece PowerFlo lift pump, contact us for a lower rate spring for your pump to accommodate operation with this kit. For higher lift pump pressures, FCA table values will require adjustment.
