SSM 50089

SSM 50089 - Various Vehicles - 3.3L, 3.5L EcoBoost, 5.0L - Stalling, Lack Of
Power, And/Or Low Fuel Rail Pressure - Fuel Jumper Line Incorrect
Installation During Service
Some 2017-2021 Ford and Lincoln vehicles equipped with 3.3L, 3.5L EcoBoost, or 5.0L engines
may exhibit stalling, lack of power, low fuel rail pressure and/or DTCs P0087 or P008A after a repair
was made that required the removal of the fuel line that connects the high-pressure fuel pump to the
port injection rail, such as injector replacements or base engine repairs. This line must be installed in
the correct orientation as it has an internal one-way check valve. To determine if the fuel line has
been installed improperly, look at the position of the Oetiker clamp (stainless band clamped around
the black fuel line). The clamp holds the one-way check valve in place and should be located closest
to the end connected to the port injection rail. If the clamp is not closest to the port injection rail,
remove and reinstall the line in the proper orientation.
