Description
Overview
The FASS Fuel Systems Factory Fuel Filter Housing Delete for 2003-2009 5.9L and 6.7L Cummins engines is the clean, purpose-built way to remove the OEM fuel filter housing once you’ve upgraded to an aftermarket fuel filtration system. Designed to fit 2003-2009 Cummins Truck/SUV applications, this delete kit swaps out the bulky factory unit for a compact delete block that tidies up your engine compartment while keeping essential functions intact.
Once you’ve installed an aftermarket fuel filtration system such as the FASS Signature Series, the factory fuel filter housing is no longer required and can be removed. This delete kit replaces that housing with a purpose-machined delete block that not only cleans up the under-hood look but also adds functionality by providing an additional return port for dual CP3 setups.
Key Benefits
Beyond the cosmetic cleanup, the delete block solves a common frustration for diesel owners running upgraded fuel systems: false water-in-fuel warnings. The water-in-fuel (WIF) sensor threads directly into a dedicated port on the delete block, keeping your dash sensor connected and preventing false water in fuel lights. That means a cleaner engine bay without giving up factory monitoring.
- Eliminates your factory fuel filter housing for a cleaner engine compartment
- Dedicated WIF sensor port prevents false water in fuel lights
- Additional return port supports dual CP3 applications
- Includes new banjo bolt sealing washers for a fresh, leak-free install
- Comes with a -6 ORB plug for single CP3 applications
- Sold as Each — Part Number CFHD1002K
Options & Configuration
This delete kit is engineered for flexibility. For single CP3 builds, use the included -6 ORB plug to seal off the extra return port. If you’re stepping up to a dual CP3 configuration, that same port becomes an additional return, giving you the plumbing you need without added adapters. Whichever route your build takes, the kit arrives ready with fresh banjo bolt sealing washers so you can complete the swap correctly.
Fitment
This FASS Filter Housing Delete is confirmed for 2003-2009 Dodge diesel trucks powered by the 5.9L and 6.7L Cummins engine. Fuel type is diesel, and engine years span 2003 through 2009.
Important note: This item is only to be used in conjunction with an aftermarket filtration system. FASS suggests pairing it with the Signature Series Fuel Systems for optimal filtration and reliable water separation. Removing the factory housing without an aftermarket system in place is not recommended, since the delete block does not filter fuel on its own.
For Cummins owners who have already committed to a serious aftermarket fuel system, this delete kit is the finishing touch that streamlines the engine bay, adds return-port capability for dual CP3s, and keeps your WIF sensor working as intended.
