Cummins and Fleetguard partnered with Catalyst to bring new life to an old product line. Steel canisters have been used to filter fuel and oil in engines for more than 80 years. Prior to this project, very few enhancements had been achieved in the design or performance of industrial fuel filters. Steel canisters have proven to be expensive, heavy and damage prone. They operate in a harsh environment of drastic temperature changes, harsh chemicals and vibration.
