Lincoln Aviator: Fuel System - General Information - 3.0L EcoBoost / Description and Operation - Fuel System - Overview
Overview
NOTICE:
Repairs of the fuel system are to be achieved only by
replacement of the failed component(s). Repair of a fuel system
component should not be attempted.
NOTICE:
If directed during assembly of fuel system components,
lubricate any seal(s) only with specified material. Failure to follow
this instruction may result in seal failure and fuel leakage.
The fuel system:
-
a Closed Loop Pressure Control (CLPC) system.
-
An 20.20 gal (76.46 L) Capacity cigar shaped fuel tank.
-
a Fuel Pump that operates on 6-12 volts variably
depending on load, that supplies fuel under pressure to the high
pressure Fuel Pump.
-
fuel and vapor lines in an integrated bundle assembly.
-
quick connect fuel and vapor tube couplings.
-
a fuel tank filler pipe assembly, which cannot be
modified in any way, that also contains a misfuel inhibitor device to
permit only unleaded fuel to be pumped into the tank.
-
has an Easy Fuel™ (capless) fuel tank filler pipe
assembly, which cannot be modified in any way and is serviced only by
the installation of a new fuel tank filler pipe assembly.
-
has a supplemental refueling adapter located inside the spare tire compartment.
-
a FPDMlocated under the vehicle on the LH side of the front floor in front of the fuel tank.
-
A Fuel Pump (FP) module containing:
-
the electric fuel pump which provides pressurized fuel to the high pressure Fuel Pump (FP).
-
the fuel level sender.
-
a check valve which maintains system pressure after the pump is shut off.
-
a pressure relief for overpressure protection in the event of restricted fluid flow.
-
a lifetime fuel filter providing filtration to protect the fuel injectors from foreign material.
Fuel Pump Shut-off Feature
In
the event of a moderate to severe collision, the vehicle is equipped
with a Fuel Pump and Sender Unit Shut-off Feature that is initiated by
the event notification signal.
The event notification signal is a signal provided by the RCM to the FPDM. Signal communication between the RCM and the FPDM allows the PCM to shut-off the Fuel Pump.
Should
the vehicle shut off after a collision due to this feature, the vehicle
may be restarted by first turning the ignition to the OFF position and
then turn the ignition to the ON position. In some instances the vehicle
may not start the first time and may take one additional ignition
cycle.
