Improve fuel filtration and make servicing your fuel filter a breeze with the XDP Cat Fuel Filter Adapter Kit. This fuel filter kit features a billet aluminum fuel filter head that replaces the stock fuel filter and allows you to mount the CAT 1R-0750 high efficiency fuel filter under the hood of your truck. Removing the stock fuel filter housing also eliminates the problematic plastic cap that is prone to breaking. Each filter head is built from an ultra-durable billet aluminum constriction and comes complete with everything needed for installation.
