Replace the weak plastic OEM fuel filter caps on your 2025+ 6.7L Cummins with WCFab’s maintenance friendly billet aluminum versions. Not only do these caps look great and really dress up the look of your engine bay, they also won’t crack with age or strip out easily. Precision CNC machined in the USA from 6061-T6 billet aluminum in house at WCFab in a design to match our other billet coolant, brake, and oil caps for your Cummins. Features easy grip styling to aid with spin on start and removal by hand. Includes a 1/2” square drive, which prevents the need for specialty tools to break the caps loose or set the final torque at the end of a filter service. Includes new o-ring seals.
Available in Black or Clear Anodized finishes to match the customized look of your truck.
