Our Titanium Series Electric Heater Kits are an upgrade for FASS Systems being used in extremely cold climates. Each FASS Titanium Series pump has 2 ports for electric heaters which help aid in cold weather starts and keep fuel from gelling while driving during extremely cold temperatures. The heater(s) will begin warming once the key is in the on position and will automatically shut off after the proper temperature has been reached. While FASS Fuel Pumps are built to start your diesel engine in the coldest of temperatures, adding a FASS Electric Heater Kit will have you geared up for whatever mother nature throws your way!
