Fleece Performance Auxiliary Heated Fuel Filter

2003–2018 Dodge Ram 2500/3500 5.9L & 6.7L Cummins Diesel

Part #: FPE-CUMM-HFFBA-0318

Overview

The Fleece Performance Auxiliary Heated Fuel Filter is a premium upgrade designed specifically for Dodge Ram 2500 and 3500 trucks equipped with 5.9L and 6.7L Cummins diesel engines from 2003 through 2018. This advanced fuel filtration system enhances fuel delivery reliability by integrating a high-flow fuel heating element and a Water-In-Fuel (WIF) sensor into the auxiliary fuel filter setup. Ideal for diesel enthusiasts and professionals who demand consistent engine performance in cold climates, this kit improves fuel accessibility while reducing maintenance costs through the use of a durable Donaldson filter element.

By combining fuel heating and water separation in one compact unit, this kit ensures cleaner, warmer fuel reaches your injection pump, minimizing the risk of fuel gelling and water contamination that can lead to engine damage or downtime.

Key Features

Engineered to optimize fuel system performance and durability, the Fleece Performance Auxiliary Heated Fuel Filter offers the following key features:

• Integral high-flow fuel heating element activates below 28.4°F and deactivates above 48.2°F to prevent fuel gelling in cold conditions
• Water-In-Fuel (WIF) sensor with adaptation harness for real-time water contamination monitoring
• Includes a 3-micron Donaldson fuel filter and water separator for superior filtration and extended service intervals
• Complete kit with push-lock hose, AN and barb fittings, and CP3 feed fittings tailored for 5.9L and 6.7L Cummins CP3 injection pumps
• Designed to work with a Fleece Performance fuel filter delete, improving fuel filter accessibility and reducing maintenance costs
• Durable mounting hardware included for secure installation
• Compatible with stock OE sending units when used with optional quick disconnect fitting (P/N: FPE-QUCON-OE-38)

Construction & Design

The auxiliary fuel filter base is precision-engineered from high-quality materials to withstand harsh under-hood environments and provide reliable long-term service. The integrated heater element is designed to deliver a consistent temperature increase of 4 to 8 degrees Fahrenheit across typical fuel flow rates, ensuring fuel remains fluid and free of wax crystals in cold weather. The Donaldson 3-micron filter media offers excellent contaminant retention, protecting your injection system from harmful debris and water intrusion. All fittings and hoses are selected for durability and leak-free connections, making this kit a robust addition to your Cummins fuel system.

Installation & Fitment

This auxiliary heated fuel filter kit is designed for direct fitment on 2003–2018 Dodge Ram 2500 and 3500 trucks with 5.9L and 6.7L Cummins diesel engines. Installation requires a pre-existing Fleece Performance fuel filter delete or the purchase of one separately. The kit does not include a quick disconnect fitting for the OE lift pump; however, if you are retaining the stock sending unit on the fuel tank, the optional quick disconnect fitting (P/N: FPE-QUCON-OE-38) is recommended for proper connection. The comprehensive hardware and fittings included simplify routing and plumbing from the Fleece Performance lift pump to the injection pump, making installation straightforward for experienced technicians or knowledgeable enthusiasts.
