2011-2016 LML CP3 Conversion Kit with Heavy Duty CP3 Fleece Performance

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. Our kit provides you with OEM fit-and-finish features like a brand new Bosch CP3 with heavy duty 10mm cam, Fleece 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.

Features

• Heavy Duty CP3 with 10mm displacement cam
• High flow CP3 feed and return fittings
• Preformed feed and return fuel hoses

Kit Contents:

• 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
• This kit has been tested for use in stock application trucks that did not utilize a fuel 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.
