Summary
Certain 2020 Model Year Super Duty and 2021 Model Year Medium Duty Vehicles Equipped with a 6.7L Engine Left Hand Side High Pressure Fuel Rail Replacement. In some of the affected vehicles, the vehicle may have been built with a high pressure fuel rail where the internal fuel orifice may become dislodged. If the fuel orifice becomes dislodged, it can travel down and damage the pressure control valve pintle resulting in a Diagnostic Trouble Code (DTC) P0088. Before demonstrating or delivering any new in-stock vehicles involved in this program, dealers are to replace the left hand side high pressure fuel rail using the technical instructions, even if DTC P0088 is not present. This service must be performed on all affected vehicles at no charge to the vehicle owner.

Why are you receiving
this notice?
On your vehicle, it may be possible one of the high pressure fuel rails was
assembled incorrectly.
What is the effect?

your dealer do?
In the interest of customer satisfaction, Ford Motor Company has authorized
your dealer to replace the high pressure fuel rail free of charge (parts and
labor) under the terms of this program.
This Customer Satisfaction Program will be in effect until November 30,
2021 regardless of mileage. Coverage is automatically transferred to
subsequent owners.
How long will it take?
The time needed for this repair is less than one-half day. However, due to
