Davco’s re-engineered Fuel Pro 483 fuel preheater for diesel engines now has internal passages and four coolant ports to allow the use of engine coolant as a heating source when the truck is on the road. Other heating options include 12- and 24-volt preheaters that preheat fuel in 6 to 10 minutes before starting the engine; and a 120-volt overnight heater that provides heat to prevent gelling when the truck is parked overnight.
