Heater Kits include a Heater Feed-Thru Assembly (wire harness) for installation.
• In double or triple manifold systems, heating elements are usually installed in each filter unit
• Heater Kits often require use of a Heater Relay Kit (eg RK 11861, RK 19490-12 - for 12V) to handle the higher current load in these heating elements (sold separately)
• Heaters are thermostatically controlled to turn on at fuel temperatures below 50°F, and turn off at fuel temperatures above 80°F
