Ford Fusion: Fuel Tank and Lines - 1.5L EcoBoost (118kW/160PS) – I4 / Fuel Tank and Lines - Overview. Description and Operation

Fuel System

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 tank and lines consist of the following:

  • single container (L-shaped) fuel tank.
  • lifetime in tank fuel filter (serviced as part of the fuel pump).
  • 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.
  • fuel tubes (liquid and vapor).
  • FPDM
  • fuel tank pressure sensor (part of the fuel vapor tube assembly).
  • fuel pump and sender.

The vehicle:

  • has a serviceable fuel level sender mounted on the fuel pump module.
  • has a fuel tank filler pipe which contains a mis-fuel inhibitor to permit only unleaded fuel to be pumped into the fuel tank.
  • has an Easy Fuel™ (capless) fuel tank filler pipe assembly, which cannot be modified in any way.
  • has a supplemental refueling adapter located in the luggage compartment.
  • has a lifetime in tank fuel filter serviced as part of the fuel pump.
  • has fuel tubes (liquid and vapor) combined in a bundle along with the brake tubes mounted on the underside of the floorpan and covered with a protective cover shield.
  • has quick connect and spring lock fuel tube couplings.
  • has a FPDM that shuts off fuel in the event of a collision.

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.

The event notification feature provides other vehicle subsystems with information pertaining to SRS deployment or fuel cutoff status. When an impact occurs which exceeds a pre-determined threshold, the RCM sends a signal on a dedicated circuit to the BCM.

When the BCM receives a crash signal input from the RCM, the BCM initiates fuel cutoff by removing the ground signal from the Fuel Pump Relay and also sends a signal to the PCM on a dedicated circuit, disabling the fuel system.

After the fuel system is disabled, the vehicle can be re-started after carrying out the following steps:

  • Turn the ignition OFF.
  • Turn the ignition to START (on vehicles with push button start, press the start/stop button while the brake pedal is pressed).
  • Turn the ignition OFF.
  • Turn the ignition ON.

    Understanding Your Tire Pressure Monitoring System

    Ford Fusion. Understanding Your Tire Pressure Monitoring System

    The tire pressure monitoring system measures pressure in your road tires and sends the tire pressure readings to your vehicle. You can view the tire pressure readings through the information display. The low tire pressure warning light will turn on if the tire pressure is significantly low. Once the light is illuminated, your tires are under-inflated and need to be inflated to the manufacturer’s recommended tire pressure. Even if the light turns on and a short time later turns off, your tire pressure still needs to be checked.
