The Standard Ignition DFH101 Fuel Injection Fuel Heater is engineered to maintain optimal fuel temperature, ensuring efficient combustion and reliable engine performance. Designed for specific Ford and International models, this component is mounted within the filter housing to effectively heat diesel fuel before injection. Constructed with high-quality materials, the DFH101 features aluminum terminals for enhanced conductivity and Viton® O-rings for superior sealing under extreme conditions. Its composite plastic housing and conductive metal heating element contribute to prolonged durability and consistent operation. This fuel heater is compatible with various Ford models, including the E-series, Excursion, F-250, F-350, F-450, and F-550 from 1998 to 2003, as well as the International 1652 from 1999 to 2007. By ensuring the diesel fuel is adequately heated, the DFH101 helps prevent issues such as fuel gelling in cold temperatures, thereby reducing maintenance costs and minimizing downtime. Its precise fit and reliable performance make it a valuable component for fleet operations, contributing to the overall efficiency and longevity of the vehicle's fuel system.
