Fuel Tank and Lines 310-01A-4 310-01A-4 DESCRIPTION AND OPERATION Fuel return system 1 8 7 E65893 Item Description 1 Fuel filter 2 Fuel line fuel return T-piece 3 Fuel pressure regulator 4 Fuel rail 5 Fuel return line 6 Fuel tank 7 Fuel jet pump 8 Fuel pump The fuel pressure at the fuel injectors is controlled by a fuel pressure regulator mounted in the fuel return system. Fuel is pumped from the fuel tank, to the fuel filter. From the fuel filter, fuel is delivered to the fuel rail. A T-piece is fitted into the fuel injector fuel supply line above the fuel tank. This T-piece acts as the fuel return line and has a fuel pressure regulator fitted in the circuit. By allowing excess fuel pressure to return to the fuel tank, a constant pressure can be maintained at the fuel injectors. 2 3 5 4 6 Fuel tank vent valves E129303 Unlike the fuel tank on vehicles with diesel engine, the fuel vapor is not permitted to vent to atmosphere. Instead the fuel vapor is collected in the evaporative emission canister until the correct driving conditions permit the fuel vapor to be burnt in the engine combustion chambers. This reduces the overall emissions from the vehicle. If the fuel tank becomes inverted, the fuel tank vent valves close preventing the evaporative emission canister being filled with fuel. If the fuel tank vent valves, fuel vapor lines or the evaporative emission canister become restricted,

Fuel Tank and Lines 310-01A-5 310-01A-5 DESCRIPTION AND OPERATION vehicle performance will become impaired. The inability of the fuel tank to substitute the fuel demanded by the fuel pump with air, will create a negative pressure in the fuel tank which could result in deformation of the fuel tank. Fuel pump and sender Unit 1 2 6 3 5 4 E129287 Item Description 1 Fuel pump and sender unit locking ring 2 Fuel pump and sender unit sealing ring 3 Sock filter 4 Fuel jet pump 5 Fuel pump 6 Fuel level sensor resistor card The fuel pump and sender are a combined unit and cannot be serviced separately. The fuel pump and sender unit is located in the top of the fuel tank and is retained by a fuel pump and sender unit locking ring and seal. The fuel pump and sender 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 pump and sender to the instrument cluster and the powertrain control module (PCM) using the controller area network (CAN) circuits. The fuel pump and sender resistor card can be susceptible to contaminated fuel, which can affect electrical continuity. This condition is normally temporary and self-rectifying. If the fuel pump and sender 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 pump and sender. 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 very slow movement of the fuel gauge pointer from empty to full over approximately 15 minutes. In more extreme cases where the resistor card resistance is continuously outside the permitted range for more than 33 seconds, a DTC will be set in the CJB and the fuel gauge pointer will fall to its key-off position. In all cases where the fuel pump and sender is suspected of being inoperative, worn or damaged, the ford diagnostic system (FDS) diagnostic procedures must be followed before any parts are dismantled. The fuel pump supplies fuel to the fuel charging system at a constant regulated pressure. The fuel pressure is controlled by the fuel pressure regulator, built into the fuel pump fuel return circuit. The fuel pump and sender also incorporates a fuel jet pump. The return fuel from the fuel charging system is passed through a venturi in the jet pump which causes a pressure drop across an open orifice. This draws in fuel through the base of the unit which then passes through the sock filter to the fuel pump.
