Some L5P 6.6L Duramax vehicles have a secondary MAP sensor. The problem: Its direct placement into the intake air stream from the factory causes the soot buildup to become an ongoing maintenance problem, requiring routine cleaning or replacement of the sensor. The solution: Fleece Performance secondary MAP sensor spacers. They move the sensor from the direct intake air stream to reduce soot buildup over time and eliminate the need to routinely clean or replace the sensor. Each kit includes mounting block (spacer), fastener, and O-ring.

The LML Duramax was not originally equipped with a fuel heater, making it prone to fuel gelling in cold temperatures. Fleece Performance auxiliary heated fuel filter kits mount in the factory location, providing for a direct factory replacement and the peace of mind to tackle the coldest of days with a high-flow fuel heater. These kits replace the factory fuel filter housing with a new filter base, integral high-flow fuel heater, Water-In-Fuel (WIF) sensor, and Donaldson spin-on canister style filter. The filter base eliminates the factory fuel primer bulb and is intended for use with a positive pressure lift pump, such as Fleece's PowerFlo lift pump or alternative frame mounted pump. Kit includes: * Fuel filter base with integral fuel heater and fittings * Donaldson 3 micron fuel filter and water separator * Pre-formed hose and hose clamps * Wiring harness and fuse taps * Water-In-Fuel (WIF) sensor and adaptation harness
