This adapter allows for the use of a FASS Electric Fuel Heater in one of our Driven Diesel Billet Fuel Filter Heads. Simply choose an available port where the probe of the heater won't obstruct flow, install the adapter into the filter head, then follow the instructions that come with the FASS Electric Fuel Heater to complete your installation. We recommend the FASS DIFSHK1001 heater kit (see Related Products tab) because it has the least extra/unnecessary parts in the package. This adapter should work with any FASS electric heater, as long as it has the same heater element as the kit we recommend.
