Product Description
If your 2010-2018 4th Gen Dodge Ram 6.7L Cummins is running an aftermarket fuel system like an AirDog or FASS, your factory fuel filter housing becomes nothing but restriction and clutter. The FLEECE FPE-FFD-RO-4G 2010-2018 4TH GEN DODGE/CUMMINS FUEL FILTER DELETE replaces the stock filter assembly with a clean, high-flow billet block that streamlines your fuel system, retains key sensors, and adds provisions for dual CP3 setups.
Designed by Fleece Performance Engineering, this kit is ideal once the factory filter is bypassed by an external filtration system. Instead of pushing fuel through an unnecessary OEM canister, you get a compact, properly machined delete block that maintains the factory fuel return line routing and gives you a clean, professional look under the hood.
- Direct replacement for the OEM fuel filter housing on 2010-2018 4th Gen 6.7L Cummins
- Perfect companion for AirDog, FASS, and other aftermarket filtration systems
- Keeps the factory fuel return lines in their proper location – no bending or relocating
- Provides a dedicated port for the factory Water In Fuel (WIF) sensor
- Includes a 9/16-18 O-ring port plug that can be used for a dual CP3 return line
- Cleans up the engine bay and reduces restriction in the fuel system

FAQ – FLEECE FPE-FFD-RO-4G 2010-2018 4TH GEN DODGE/CUMMINS FUEL FILTER DELETE
Do I still have fuel filtration with this installed?Yes – if you have an aftermarket fuel system such as an AirDog or FASS that provides proper filtration. This block is designed specifically for trucks where the factory fuel filter has already been bypassed. It does not provide its own filtration; it simply removes the now-unused factory housing and reduces restriction.
Can I run this on a completely stock fuel system?
No. The FPE-FFD-RO-4G is not intended for trucks that still rely on the factory fuel filter for primary filtration. You must have a complete aftermarket filtration system in place before installing this delete block, otherwise you risk running unfiltered fuel to your CP3 and injectors.
What is the 9/16-18 O-ring port used for?
Fleece includes a 9/16-18 O-ring port that is commonly used for a dual CP3 return line. This makes the delete block a perfect base for dual pump setups, allowing you to tie in return fuel cleanly without hacking factory lines or adding extra tees.
Does this retain the factory Water In Fuel (WIF) sensor?
Yes. The block provides a port for the factory WIF sensor so you can maintain that safety feature and continue to monitor for contamination. A plug is also included in case the WIF sensor is not used in your particular configuration.
Is tuning required after installing the fuel filter delete?
No tuning is required just to install the fuel filter delete. However, because this part is almost always installed alongside higher-flow lift pumps and often dual CP3 setups, your overall combination may benefit from proper calibration to manage rail pressure, drivability, and emissions compliance.
