Fuel Tank and Lines – 2.2L Duratorq-TDCi (88kW/120PS) - Puma/2.2L Duratorq-TDCi (96kW/130PS) - Puma/2.2L Duratorq-TDCi (110kW/150PS) - Puma/3.2L 310-01B-4 310-01B-4 Duratorq-TDCi (148kW/200PS) - Puma DESCRIPTION AND OPERATION Item Description 13 Breather pipe 14 Fuel tank filler pipe 15 Fuel cooler Fuel tank vent valves E128985 Fuel tank ventilation is achieved by two fuel tank vent valves. The fuel tank vent valves are integral to the fuel tank and will prevent fuel loss from the fuel tank if the vehicle becomes inverted. Under normal working conditions, the pressure within the fuel tank is controlled by allowing the fuel vapor to vent through the fuel tank vent valves to atmosphere. If the fuel tank becomes inverted, the fuel tank vent valves close preventing fuel being lost from the fuel tank. If the fuel tank vent valves or the fuel vapor lines connected to the vent valves become restricted, vehicle performance will become impaired. The inability of the fuel tank to substitute the fuel demanded by the fuel charging system with air, will create a negative pressure in the fuel tank which will result in reduced fuel flow to the fuel pump.

The fuel level sensor consists of a mechanical float attached to a variable resistor card by means of a rigid wire lever. The resistor card has two electrical elements. One element is solid and one element is a variable resistor. The resistance value created by the resistor card is sent to the central junction box (CJB) through a hard wired circuit. The CJB distributes the information from the fuel level sensor to the instrument cluster and the powertrain control module (PCM) using the controller area network (CAN) circuits. The fuel level sensor resistor card can be susceptible to contaminated fuel, which can affect electrical continuity. This condition is normally temporary and self-rectifying. If the fuel level sensor has been removed, moving the rigid wire lever from empty to full a minimum of 10 times will normally be as effective as installing a new fuel level sensor. The most common symptom of contamination occurs after refuelling where the electrical contact moves to an area of the resistor card which has not been used for several days. This results in a
