Parker Racor's RK6165804 Return Fuel Heat Valve features innovative patented technology that utilizes unused warm engine fuel returning to the tank to provide on-demand fuel heat transfer for cold weather operations. This cold weather feature melts the wax and paraffins that separate from diesel fuel at cold temperatures (cloud point) and restrict fuel flow during the filtration stage. The recirculating valve is self-regulating, sensing fuel temperature and automatically closing once the fuel is warm, and returns hot fuel to the tank. Used with GreenMax Fuel Filter Water Separators.
Note: Valve only. GreenMAX Fuel Filters/Water Separators sold separately.
