Fits select 2010-2018 Dodge and Ram 2500 and 3500 trucks (5.9L / 6.7L).

The Fleece Performance 4th Gen Fuel Filter Delete is an essential upgrade for Cummins owners running high-flow aftermarket filtration systems like an Air Dog or FASS. Once an external system is in place, the factory fuel filter housing becomes a redundant restriction and a source of engine bay clutter. This delete block removes that bottleneck, improving flow and cleaning up the under-hood environment.

Designed for a direct-fit installation, this block mounts perfectly to allow the use of factory fuel return lines without the need for bending or relocating. It features a dedicated port for the factory Water In Fuel (WIF) sensor and a 9/16-18 O-ring port to accommodate a dual CP3 return line, making it a versatile solution for both street and high-performance builds.

Fits 2011-2024 Ford F-250 and F-350 Super Duty (6.7L Powerstroke).

The Fleece Performance Under Hood Fuel Filter Bypass is a robust solution for 6.7L Powerstroke owners who have upgraded to an aftermarket lift pump or auxiliary fuel filtration system. The factory plastic under-hood filter housing is known to be crack-prone; this bypass eliminates that potential failure point while simplifying your fuel system plumbing. It is a direct, drop-in replacement that requires no cutting, splicing, or permanent modification of your original equipment (OE) fuel lines.

Engineered for versatility across the 6.7L engine's lifespan, this kit includes everything needed for a seamless install. For 2011-2016 trucks, the bypass utilizes a standard inlet and outlet configuration. For 2017-2024 models, an additional quick-disconnect fitting is provided to handle the required fuel return line. This component is machined from billet aluminum and anodized for long-term durability in harsh engine bay environments.

• Replaces crack-prone factory plastic under-hood fuel filter housing
• Direct drop-in installation with no fuel line modifications required
• Precision-machined billet aluminum bypass block with black anodized finish
• Includes heavy-duty quick-disconnect fittings for a secure seal
• Accommodates both early (2011-2016) and late (2017-2024) fuel return configurations
• Manufacturer Part Number: FPE-FMC-FFB-1124

Note: This bypass removes the factory under-hood filtration and should only be used in conjunction with an auxiliary fuel filtration system (such as FASS or AirDog) that meets or exceeds OEM filtration specifications.

Fits 2007-2009 Dodge Ram 2500 and 3500 trucks (6.7L Cummins).

Streamline your fuel system and eliminate unnecessary restrictions with the Fleece Performance fuel filter delete. If your truck is equipped with an aftermarket lift pump and filtration system—such as an Air Dog or FASS—the factory fuel filter housing is no longer required. Retaining the OE housing only creates a bottleneck in your fuel flow and clutters the engine bay. This delete block allows you to remove the factory canister while maintaining clean, organized plumbing.

Engineered for a precise fit, the block mounts to factory locations to allow the use of original fuel return lines without bending or relocating. It includes a dedicated port for the factory Water in Fuel (WIF) sensor and a 9/16-18 O-ring port for those running a dual CP3 setup.
