Cold temperatures are the number one killer of diesel fuel and its ability to properly combust, or simply flow for that matter. Contrary to gasoline, when diesel gets cold, it gels up, inhibiting its ability to flow, especially through a lift pump or your injectors. This upgrade kit works in conjunction with your AFE DFS780 Fuel System to ensure frigid temperatures are never the culprit for your truck not starting.
Make sure your diesel is prepared to perform in the coldest conditions with aFe's DFS780 Fuel System Cold Weather Kit. The kit works with DFS780 and DFS780 PRO diesel fuel systems and easily plumbs into your engine's cooling system to warm the fuel to keep it from gelling in freezing temperatures. Heater hose not included
