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

PowerFlo is the latest OEM replacement performance in-tank lift pump from the diesel experts at Fleece. It's the only in-tank lift pump capable of supporting up to 800 hp, including dual CP3 pump configurations! The PowerFlo assemblies retain the factory water-in-fuel sensor, factory fuel heater, and factory fuel lines—and installation takes half the time of other high-flow pumps. Two is always better than one, and the PowerFlo delivers with two OEM-quality gerotor pumps, increasing flow capacity and reliability over the factory pump. The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank issues typically encountered when seeking a higher flow lift pump to meet your engine's need. Order the Fleece Performance PowerFlo in-tank lift pump assembly recommended for your vehicle.

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.

Upgrade your fuel system with these Fleece Performance fuel filter delete blocks. If you have an aftermarket fuel filtration system, such as an Air Dog or a FASS, your factory fuel filter is no longer necessary—is only becomes an extra restriction and an eyesore. These delete blocks will remove that restriction and help clean up under the hood of your truck. They mount perfectly to allow the factory fuel return lines to be used without any relocating or bending. The blocks also feature a port for the factory WIF (water in fuel) sensor and a 9/16-18 O-ring port for a dual CP3 return line.

Fleece Performance regulated return systems take their standard fuel distribution blocks to the next level by fully integrating a high-flow pressure regulator. This feature, in combination with high-flow aftermarket electric fuel pumps (without built-in pressure regulation), provides more consistent fuel pressure at the CP3. The kits also have one additional return line port and one additional feed line port. The extra return line port allows you to remove the factory fuel pressure relief valve hard line and fuel injector return galley hard line to provide clearance for high-flow side draft intakes, common on competition engines. If you're looking for something beyond your average fuel distribution block, Fleece Performance regulated return systems are your answer.

Earl's Performance Dominator in-line billet fuel pumps are for those of you who are in need of a fuel pump that can support serious horsepower. Have a nitrous system, turbo or supercharger? No problem! These fuel pumps feature a twin-pump design that allows you to use one pump for cruising and both pumps when you activate your nitrous switch or start building boost. The second pump allows you to eliminate the unnecessary recirculating and heating of fuel that can lead to poor performance and hot fuel issues. Earl's Performance Dominator in-line billet fuel pumps also have an added benefit for hard core enthusiasts that run events like the Hot Rod Power Tour or the Baja 1000; that extra pump brings you peace of mind that you'll always finish what you've started. Features include: * Billet aluminum construction for durability and good looks * -10 AN O-ring inlet/outlet for high flow and superior sealing * Suitable for use with carbureted or EFI applications * May be fully submerged in-tank for custom applications, space savings, and reduced plumbing * Compatible with 12 V to 18.5 V systems at pressures up to 80 psi for street or race use * For hardcore race use, both pumps can be wired for full-time duty * Only 7.66 in. long x 5 in. wide x 2.5 in. tall for easy installation on frame rails or other tight areas * Patent pending dual-pump technology * Proven durability beyond 3,000 hours * Weighs only 5.1 lbs.--half a pound less than competitive 1000+ hp pumps * Not for use on aircraft of any type Note: These pumps are not designed to use standard conical seat-style unions in the inlets or outlets of the pumps. Use of this style fitting will block flow and WILL lead to poor performance and pump failure. The ONLY correct fitting to use is a contoured port fitting with an O-ring seal such as part # EAR-AT985010ERL.
