Recall 16V778 covers 170 2017 Ford F-250 Sd, F-350 Sd, F-450 Sd, and F-550 Sd trucks. Free shield replacement at Ford dealers.
Ford is recalling 170 2017 F-250 Sd, F-350 Sd, F-450 Sd, and F-550 Sd trucks because the protective shield on the fuel conditioning module can come loose. If the shield dislodges, the drain valve can open and leak fuel, which increases fire risk near an ignition source and leaves liquid fuel on the road, a slip hazard that increases crash risk; Ford dealers will complete the free repair.

What's wrong?
The fuel conditioning module on the 2017 Ford F-250 Sd, F-350 Sd, F-450 Sd, and F-550 Sd diesel trucks is part of the fuel system under the fuel tank. It helps manage diesel fuel before it reaches the engine, and its drain valve is protected by an adhesive-mounted shield. That shield is supposed to stay attached so road splash and debris do not hit the drain valve.
On affected trucks with a 6.7L diesel chassis cab layout and middle position fuel tank, the shield adhesive does not hold strongly enough under certain driving conditions. Road splash at certain speeds can dislodge the shield. Once the shield moves, splash or debris can contact the drain valve and damage it or open it, causing fuel to leak from underneath the tank.
Owners can notice fuel odor or visible fuel leaking under the truck. Air entering the fuel system can also make the engine stumble or cause other driveability symptoms.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A dislodged shield can open the drain valve and create a fuel leak. Fuel near an ignition source increases fire risk, and enough liquid fuel on the road can create a slip hazard that increases crash risk. Watch for fuel odor, visible leaks, engine stumble, or other driveability changes, and schedule the repair soon. Repair is free at any franchised Ford dealer.
What should I do?
- Check your VIN to confirm your 2017 Ford F-550 Sd, F-350 Sd, F-450 Sd, or F-250 Sd is included in this recall.
- Contact a franchised Ford dealer to schedule the free protective-shield replacement that secures the fuel conditioning module shield over the drain valve.
- Bring the recall notice if Ford mailed one, and reference recall number 16V778 (Ford recall 16S39) when you call.
- Watch for diesel fuel under the truck or a fuel smell, and stop driving if you see or smell fuel.
What happens at the repair
At the dealer, a Ford technician replaces the protective shield on the fuel conditioning module so the shield stays secured in place. Parts and labor are covered under the recall, and the repair is free at a Ford dealer now. Ford is not offering a separate reimbursement program because the original warranty program provides a free repair for this concern. If you have prior repair paperwork, ask the service desk how the original warranty applies.
