Sinister Diesel Fuel Filter Conversion Kit

The Sinister Diesel Fuel Filter Conversion Kit permanently eliminates the weak point of plastic housing by coming out with a CNC-machined billet aluminum housing. This housing is built to handle pressure, heat, and long-term use.

Filtration quality is just as critical as housing strength. Sinister Diesel partnered with Baldwin to select the 4-micron nominal filter because it aligns with OEM filtration standards while maintaining proper flow characteristics for the high-pressure common-rail fuel system. Many competing kits use 9+ micron filters - which allow significantly more particulate matter to pass through compared to a 4-micron filter.

Sinister Diesel’s housing was engineered from the beginning to support both 2-port and 3-port configuration for the fuel system. To secure the housing, Sinister Diesel uses a Buna O-ring locking system that provides a clean, secure seal into the factory cup.
