The Davco Technology Fuel Heater is a 12 VDC / 150 W PTC pre-heater designed to help prevent diesel fuel from gelling in cold weather. It warms the fuel before it reaches the filter or injection system, ensuring fuel stays fluid and pumpable in freezing conditions. With a 7.50‑inch harness and standard thread connection, this heater is easy to integrate into existing fuel filter or water‑separator setups. For trucks that operate in cold climates, installing the Davco Technology 103706DAV heater supports more reliable engine starts and reduces the risk of fuel‑flow problems during winter.
