Upgrade your 5.9 Cummins fuel filtration with the XDP XD232 CAT Filter Adapter. This high-quality billet aluminum adapter is designed to work seamlessly with your existing factory fuel lines, allowing you to use the superior CAT 1R-0750 filter. With 2-micron filtration, it ensures your engine receives the cleanest fuel possible, enhancing performance and longevity. The CAT Filter Adapter replaces the factory filter housing, so it’s not compatible with early model trucks that have the lift pump mounted to the fuel filter housing. Keep your Cummins running smoothly with this easy filtration upgrade.
