FLEECE FPE-DMAX-HFFBA-1116 AUXILIARY HEATED FUEL FILTER KIT FOR 2011-2016 LML DURAMAX

Introducing our all-new full featured auxiliary fuel filter kit for the 2011-2016 LML 6.6L Duramax! This kit replaces 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 our PowerFlo lift pump or alternative frame mounted pump.  

Problem: The LML Duramax was not originally equipped with a fuel heater, making it prone to fuel gelling in cold temperatures.
Solution: Our updated fuel filter base mounts 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.

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 

Fuel heater specifications:

• Temperature switching points: ON: 28.4F +/-5.4F,  OFF: 48.2F +/- 5.4F
• At typical fuel flow rates a temperature increase of between 4-8F will occur across the heating element

Application Notes:

• For 2011-2016 6.6L Duramax only
• This filter base eliminates the factory fuel primer bulb and is intended ONLY for use with a positive pressure lift pump such as our PowerFlo lift pump or alternative frame mounted pump.  

The FLEECE FPE-DMAX-HFFBA-1116 Auxiliary Heated Fuel Filter Kit enhances the performance and reliability of your 2011-2016 LML 6.6L Duramax diesel engine, addressing a critical issue – fuel gelling in cold temperatures. This innovative kit replaces the factory fuel filter housing with a state-of-the-art filter base encompassing a high-flow fuel heater, a Water-In-Fuel (WIF) sensor, and a premium Donaldson spin-on canister style filter.

Designed for seamless installation, the filter base mounts directly in the factory location, providing an exact fit. It eliminates the need for the stock fuel primer bulb, functioning optimally with positive pressure lift pumps like the PowerFlo or any compatible frame-mounted pump. This ensures a reliable and efficient fuel delivery system, even in the harshest winter conditions.

A core feature of the kit is its integral fuel heater, designed to activate at an ambient temperature of 28.4°F and deactivates at 48.2°F, ensuring your fuel remains free-flowing when you need it most. The heater raises the fuel temperature by 4-8°F during normal flow, significantly diminishing the risk of gelling.

Included in the kit are essential components such as the fuel filter base with fittings, a durable Donaldson 3-micron fuel filter for optimal filtration and water separation, pre-formed hoses with clamps, a wiring harness with fuse taps, and a complete WIF sensor adaptation harness.

This auxiliary heated fuel filter kit is specifically engineered for the LML Duramax, setting a new standard in cold weather performance, reliability, and ease of installation. Equip your Duramax with this essential upgrade and experience peace of mind, knowing you can tackle extreme conditions with confidence.
