xd171

The XDP Duramax CAT Adapter with 1R-0750 Filter, Bleeder Screw & Spacer is an easy way to upgrade the factory fuel filter on your 2001-2015 GM 6.6L Duramax. The durable anodized filter adapter simply threads on to the OEM Filter Head and allows you run the more efficient and less expensive CAT Filter on your truck. For an even easier filter change, we also include a filter head spacer to give you more clearance for filter changes, along with an aluminum bleeder screw to replace the factory supplied plastic version that is commonly damaged during routine maintenance.

XDP Part Number: XD171

Step 1: If equipped, disconnect the factory fuel filter heater wire on the top of the factory fuel filter head.

Step 8: Lubricate the CAT filter seal and hand tighten onto the adapter.

4Step 9: Replace the plastic factory air bleeder screw with the new aluminum bleeder screw. (Fully tightening the new bleeder screw, prime the filter by depressing the priming pump 4-5 times and loosen the screw to bleed off the air. You may have to do this a few times until all air is completely out of the system.)

Step 10: Tighten your air bleeder screw, start the engine and check for any leaks. (If you have issues holding a prime, remove the adapter/filter and re-lube the O-ring/seal to ensure you have a good seal.)
