Fleece Performance FPE-DMAX-HFFBA-1116 Heated Fuel Filter Kit 2011-2016 LML Duramax

The Fleece Performance FPE-DMAX-HFFBA-1116 is a complete auxiliary fuel filter system designed specifically for 2011-2016 LML 6.6L Duramax engines. This comprehensive kit replaces the factory fuel filter housing with an upgraded filter base featuring an integral high-flow fuel heater, Water-In-Fuel (WIF) sensor, and Donaldson spin-on canister style filter for superior fuel filtration and cold weather protection.

Cold Weather Protection:

The LML Duramax was not factory-equipped with a fuel heater, making it vulnerable to fuel gelling in freezing temperatures. This kit solves that problem with a built-in high-flow fuel heater that automatically activates at 28.4°F (±5.4°F) and deactivates at 48.2°F (±5.4°F), providing a temperature increase of 4-8°F across the heating element at typical fuel flow rates. Mount it in the factory location for a direct replacement that gives you confidence in the coldest conditions.

Complete Kit Includes:

• Fuel filter base with integral fuel heater and fittings
• Donaldson 3-micron fuel filter and water separator
• Pre-formed hoses and hose clamps
• Wiring harness and fuse taps for heater installation
• Water-In-Fuel (WIF) sensor with adaptation harness

Important Application Notes:

This filter base eliminates the factory fuel primer bulb and is designed exclusively for use with a positive pressure lift pump, such as the Fleece Performance PowerFlo lift pump or other frame-mounted aftermarket fuel pump systems. Not compatible with stock fuel delivery systems. Fits 2011-2016 LML 6.6L Duramax engines only.
