Sogefi Secondary Diesel Fuel Filter Leak
The Office of Defect Investigations (ODI) has received 27 complaints alleging diesel fuel leaks due to a fracture in the secondary fuel filter housing in model year (MY) 2015-2021 Ford Motor Company (Ford) F-250, 350, 450, and 550 Super Duty vehicles equipped with 6.7L diesel engines. Of these complaints, 12 describe an engine compartment fire. The proximity of the secondary fuel filter to high heat sources creates a potential for autoignition thermal events and fires. ODI has contacted the vehicle manufacturer, Ford, and the filter manufacturer, Allevard Sogefi USA (Sogefi), and learned that the low-pressure fuel system is capable of a maximum operating pressure of 8.5 Bar, while the secondary fuel filter is only tested to seven (7) Bar during the manufacturing process. Additionally, changes starting in 2022 by both Ford and Sogefi align with a lack of similar complaints on MY 2022 and newer vehicles. ODI is opening this Preliminary Evaluation (PE) to evaluate the severity of the potential problem and to fully assess the potential safety-related problems.

Kept smelling faint diesel fuel odor would come and go while driving for 11,000 miles, never saw a leak, then became worse and saw drops on driveway size of a dime. Found a steady drip of fuel only while running from fuel filter under hood above valve cover, replaced filter and leak stopped. Closer look found heavy stains from fuel leak on top of engine. Has been that way since new. Leak now fixed. This could be a fire hazard. Glad I found it.
