Ford Ecosport: Fuel System - General Information - 2.0L Duratec-HE (129kW/175PS) / 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 consists of:
-
Fuel, vapor and brake tubes in an integrated bundle assembly.
-
A singular "saddle type" fuel tank.
-
Quick connect fuel and vapor tube couplings.
-
A fuel tank filler pipe assembly, which cannot be modified in any way.
-
A single speed mechanical returnless fuel system.
-
An integrated Fuel Pump and Sender Unit, comprised of:
-
An electric FP module which provides low pressure fuel to the fuel lines.
-
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 fuel system from foreign material (if equipped).
Fuel Pump Shut-off Feature
NOTE:
Refer to the Description and Operation, Intelligent
Access with Push Button Start in Section 419-01A to review the
procedures for achieving the various ignition states (ignition OFF,
ignition in ACCESSORY, ignition ON and ignition START) on vehicles with
this feature.
In
the event of a moderate to severe collision, the vehicle is equipped
with a Fuel Pump and Sender Shut-off Feature that is initiated by the
event notification signal.
The
event notification feature provides other vehicle subsystems with
information pertaining to restraint system deployment or fuel cutoff
status. When an impact occurs which exceeds a predetermined threshold,
the RCM (restraints control module) sends a signal on a dedicated
circuit to the BCM (body control module). The BCM then sends a signal on
a second hard-wired circuit to the PCM (powertrain control module),
which initiates fuel cut-off and disables the fuel system.
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.

Acceptable Noise, Vibration and Harshness (NVH)
Noise is any undesirable sound, usually unpleasant in nature. Vibration
is any motion, shaking or trembling, that can be felt or seen when an
object moves back and forth or up and down. Harshness is a ride quality
issue where the vehicle's response to the road transmits sharply to the
