CAT 1R-0749 Fuel Filter
NOW IN STOCK
CAT Replacement Filter used in conjunction with the Duramax Fuel Filter Adapter. With a 2 micron rating, this filter offers 2x the filtration over the 4 micron factory filter.
FASS lift pump replacement: This filter has a 11" case length and will hang lower than the FASS filter or 1R-0750 filter
NOTE: This will not fit the factory location of the 11+ trucks due to the length. To run this filter in the factory location on 01-10 trucks, you must have the adapter AND spacer plate that goes on the filter housing to push the housing away from the engine. The plate is necessary for clearance from the manifold.
