Ford Diesel Fuel System Recalls Involve Leaks and Pump Failure
High-pressure fuel pump failure repeats in Ford's diesel notices, while a separate recall addresses leaking fuel filters. The pump notices describe biodiesel deposits on pump drivetrain roller components that could cause pump failure and loss of drive power. Recall 24S78 names certain 2020-2022 F-250, F-350, F-450, F-550 and F-600 trucks, plus 2021-2022 F-650 and F-750 vehicles. Recall 26S17 names certain 2020-2022 F-250 through F-550 trucks, 2021-2022 F-600 and 2022 F-750 vehicles previously repaired incorrectly under 24V957. The separate 22S01 notice covers certain 2021 F-250 through F-750 models with 6.7L diesel engines and a secondary fuel filter cap that may develop a pinhole leak.
Warning signs to watch for
- Fuel pump recalls 24S78 and 26S17: high-pressure fuel pump failure can cause loss of drive power.
Can you keep driving? What the notices say
None of the three listed Ford diesel notices tells owners to stop driving or park outside. The 2021 truck fuel filter recall, 22S01, does not give either instruction. The fuel pump recall identified as 24S78 likewise does not tell owners to stop driving or park outside. The 2026 fuel pump recall, 26S17, also does not give a stop-driving or park-outside instruction. These are the driving and parking directions stated in the supplied notices for this group.
What the free repair involves
For 22S01, dealers replace the primary and secondary fuel filters free of charge. For fuel pump recall 24S78, dealers update both powertrain control module and transmission control module software free of charge. For 26S17, the specified free remedy is a powertrain control module software update.

Common questions
Do the diesel fuel pump recalls specify replacing the pump?
The supplied remedies specify software updates. Recall 24S78 calls for powertrain control module and transmission control module updates, while 26S17 calls for a powertrain control module update. Both notices state that their specified dealer remedies are free of charge.
Which trucks have the fuel filter cap leak recall?
Recall 22S01 names certain 2021 F-250, F-350, F-450, F-550, F-600, F-650 and F-750 vehicles equipped with 6.7L diesel engines. A void in the secondary fuel filter cap may progress to a pinhole that allows fuel to leak.
Why does the 2026 fuel pump notice mention an earlier repair?
Recall 26S17 explicitly covers certain vehicles previously repaired incorrectly under recall 24V957. It describes biodiesel deposits that could cause high-pressure fuel pump failure and specifies a free powertrain control module software update as its remedy.
