The XDP Fuel Filter Adapter & Filter Delete 0-Ring XD228 is a replacement O-Ring Seal for the XDP Fuel Filter Adapter XD171, or the XDP Fuel Filter Delete for your 2001-2016 GM 6.6L Duramax. While the original seal provides a long service life, having a replacement in your tool box is always a good idea. Many customers choose to replace it while rebuilding their fuel filter head, or freshening up other fuel system components as their truck ages.

This is the large 0-Ring that goes on the top of the DP Fuel Filter Delete, or XDP Fuel Filter Adapter Kit and seals up against the surface of your factory fuel filter head.
