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

Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications. Most Walbro in-tank fuel pumps utilize a proven gerotor design. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed. Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately.

Aeromotive Phantom direct-fit fuel pumps are drop-in systems engineered for your late model truck. They're available in five pump sizes, from single 340 lph to triple 450 lph. Designed to work with plastic fuel tanks, Phantom Series pumps cover a range of GM truck models spanning decades. The 1999-2004 models used a smaller factory fuel sending unit than the later 2005-17 models. The smaller size unit limits the pump configurations that this tank will accommodate. Aeromotive Phantom direct-fit fuel pump systems are also compatible with different tank depths.

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.

Standard Motor fuel pressure regulators ensure that your vehicle's fuel supply is precisely metered for optimum mileage and performance. Defective fuel pressure regulators most often develop excessive pressures that create an overly rich air/fuel mixture, robbing mileage and performance. Similarly, if the pressure regulator diaphragm leaks through its vacuum hose into the engine intake manifold, the fuel mixture will also become extremely rich. Don't take chances with your fuel supply—rely on Standard Motor Products for your vehicle's fuel system needs. Order the replacement regulator designed for your application.
