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

Fleece Performance CP3K Fuel Pump Kits

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.

Fleece Performance SureFlo Performance Sending Units

If you are running an aftermarket pump that is mounted external of the fuel tank, you will need to install a draw straw or drill your fuel tank to accommodate a sump. Each of these has some significant drawbacks including the 1/4 tank issues that result in cavitation of the pump when you draw air into the fuel system. To resolve this issue there are Fleece Performance SureFlo performance sending units. SureFlo units are designed to work with aftermarket lift pumps and fit directly into your stock sending unit location. Each one features factory-style quick disconnects to adapt your stock fuel lines at the tank, giving you the cleanest installation available, and requiring no cutting or drilling of the tank. SureFlo works by drawing fuel from, and returning fuel to, the bucket assembly at the base of the unit, ensuring you are always drawing fuel into your pump and not drawing air into the fuel system, as well as eliminating the dreaded 1/4 tank problems. The SureFlo bucket also incorporates one-way check valves to allow fuel to easily flow in at lower levels. Fleece Performance SureFlo performance sending units are a great alternative for trucks originally equipped without an in-tank pump needing to repair a malfunctioning level sender or if you are simply looking to run your own custom fuel lines directly to the tank. Choose the SureFlo unit designed for your Cummins or Duramax fuel system. Features: * New fuel level electronics and fuel float * Heavy-duty billet aluminum cap * Universal -8 AN ports for professionally plumbing a custom fuel setup * New O-ring or flange seal * Adaptation pigtail connector (where applicable)
