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.

Due to the routing, exposure, and general lack of protection on the small charging circuit sense wires that are routed from Powertrain Control Module (PCM) to the alternator, it is common for wire damage to be experienced.

These harness solutions are drop replacements—no cutting or splicing--for failed factory harnesses causing the problem. Each one installs directly in-line with factory connections, allowing you to reroute the alternator connection along the top side of the engine, and avoiding the unprotected channel routing on the underside of the engine. Designed and produced in-house, Fleece's manufacturing process includes fully automated wire cutting and terminal crimping to ensure you get the highest quality replacement parts you need to get your truck back on the road quickly.

Here's the problem: On the L5P Duramax, because of the direct placement of the MAP sensor into the intake air stream from the factory, soot buildup becomes an ongoing maintenance problem. This requires the sensor to be routinely cleaned or replaced. The solution is Fleece Performance MAP sensor spacer kits. Fleece's spacer moves the sensor from the direct intake air stream to reduce soot buildup over time and eliminates the need to routinely clean or replace the sensor. The spacer block also integrates a 1/8 in. NPT port to allow for installation of an auxiliary boost pressure sensor. Fleece Performance kits include mounting block, fastener, seal ring, and O-ring port plug.

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.
