The DFS780 Fuel System Cold Weather Kit is a system used in very cold climates and weathers, it is used to prevent diesel fuel from gelling and clogging up your fuel system in cold weather by dispensing heat through direct contact with the diesel fuel. This kit uses the vehicle's stock 5/8" heater hoses and consumers may have to source for it locally if their vehicle uses a different size, for the kit does not come with it. The fittings and clamps are of competitive quality and are included to ease installation. The kit also comes with the Power Pro Guard D2 high efficiency filter from aFe that filters the fuel and removes contaminants down to the degree of one micron. The device was made in the U.S.A.
