Detailed Description

Standard Ignition DFH104 is engineered for diesel fuel heater service in Ford applications where the heater is mounted in the filter housing. The steel body and zinc-coated finish support durability in fuel-system environments, while the conductive terminal and heater element materials are selected to maintain electrical performance during operation. This part cross-references AP63409 and F5TZ9J294A for the same application. It is a practical replacement choice for Ford E-350 Econoline, Ford E-350 Econoline Club Wagon, Ford F-250, Ford F-250 HD, and Ford F-350 diesel fuel heater service.

Vehicle Fitment

• Fits 1994-1997 Ford E-350 Econoline, mounted in filter housing.
• Fits 1994-1997 Ford E-350 Econoline Club Wagon, mounted in filter housing.
• Fits 1997 Ford F-250 HD, mounted in filter housing.
• Fits 1994-1997 Ford F-350, mounted in filter housing.
• Fits 1994-1996 Ford F-250, mounted in filter housing.

What It Helps Address

• Hard starting caused by inadequate diesel fuel heating
• Fuel gelling concerns in cold-weather operation
• Intermittent heater performance from a worn OE unit
• Corrosion-related electrical resistance at the heater terminal
• Filter-housing heater replacement needs on Ford diesel applications

Installation Notes and Tips

Install DFH104 in the original filter-housing location and verify the electrical connection is clean and secure before returning the vehicle to service. Confirm the existing heater style and mounting arrangement against the vehicle’s original part before installation. For Ford E-350 Econoline, Ford F-350, and Ford F-250 diesel applications, matching the filter-housing configuration is important for proper fit.

Quality Assurance

Standard Ignition supplies this part as a new OE-style replacement built to match the original application requirements for diesel fuel heater service.
