Filler Hose

Service the fuel tank filler pipe with utmost safety by staying away from fuel components both flames and smoking because the region contains volatile mixtures. The procedure for fuel tank repairs requires a cap or tape to cover all liquid and vapor fuel openings but they must be removed before final installation. To start the procedure use neutral mode and place a hoist beneath the vehicle. Take these steps for service on the fuel tank filler pipe by disconnecting the battery ground cable while opening the fuel tank filler cap. Reinstall the fuel tank filler cap bolts using 2 Nm (18 lb-in) torque then tighten each of the three bolts before completion. The two tabs situated on the fresh air vent tube in the fuel filler door pocket must be pressed down to detach it from the inner fenderwell. Commence by disconnecting the fuel pressure sensor vapor tube coupling to the fuel filler pipe vapor tube assembly and then proceed with taking off the rear axle vent hose and the dust separator hose. To remove the fuel tank filler pipe hose, loosen the clamp and disconnect the hose and reinstall it by tightening the clamp to 3 Nm (27 lb-in). Gently tighten the two mounting bolts of the fuel tank filler pipe assembly to 15 Nm (11 lb-ft) torque specifications during the installation process. Complete the installation process by performing the reverse actions of the removal procedure.

Avoid smoking and open flames near the fuel components because the system houses flammable mixtures when servicing the fuel filler hose. The fuel system pressure needs to be relieved before removing any fuel lines or components because it helps to stop accidental fuel spraying. Users should start the process by placing the vehicle on HOIST equipment in NEUTRAL and disconnecting the battery ground cable. When putting back the fuel filler pipe attach its screws tightly to 2 Nm (18 lb-in) torque. The two bolts securing the fuel filler pipe need to be removed from their frame position until you reach torque specifications of 20 Nm (15 lb-ft) for installation. You should disconnect the fuel filler pipe from the fuel tank hose as well as the vapor tube from the dust separator and the rear axle vent hose. Early build vehicle owners need to access the fuel vapor tube through their right-hand rear wheel well and detach it from the fuel vapor tee followed by unclipping the hose retainer from the fuel tank shield. Users can disconnect the fuel vapor vent tube from the inner fenderwell by depressing both tabs on the cable inside the fuel filler door compartment of late build vehicles. For the installation process reverse the steps of removal by reinstalling the fuel filler pipe before completing the procedure.

Service and repair operations for the fuel filler hose require first removing the fuel tank filler cap as well as all screws. Start servicing the fuel filler hose by disconnecting it from the fuel tank along with disconnecting the fuel tank vent hose from the dust separator and differential vent hose. The service process starts by disconnecting the lower fuel filler hose from the fuel filler intermediate tube and removing it while separating the upper fuel filler hose from the fuel filler tube. First disconnect the fuel filler hose by removing the tie strap and then disconnect the fuel filler hose and take out the upper fuel filler tube. First remove the upper fuel filler hose from the fuel filler intermediate tube before taking away the component. To finish the task you need to remove both tie straps and fuel filler intermediate tube along with its bolts. Follow the opposite sequence of steps for reassembling the fuel system.

A suitable starting point for servicing or repairing the fuel filler hose requires a NEUTRAL-parked vehicle on a hoist. Disconnect the negative terminal of the battery while opening the fuel tank cap. Use a torque wrench to attach and tighten the fuel tank filler cap three bolts with 1 Nm (9 lb-in) force before cap reinstallation. To work on the fuel filler hose of Explorer and Mountaineer models users must depressing the two tabs that secure the fresh air vent tube in the fuel door pocket to inner fenderwell. To begin the procedure disconnect the fuel filler pipe vapor tube first from the fuel pressure sensor and the vapor tube assembly quick connect coupling and then proceed to disconnect both the rear axle vent hose and the dust separator hose. Loosen and disconnect the fuel tank filler pipe hose with a clamp that will need tightening to 3 Nm (27 lb-in) when reassembling. The two bolts that attach the fuel tank filler pipe assembly must be removed although installation demands bolt torque be set to 15 Nm (11 lb-ft). The complete installation process requires you to reverse all steps of removal. Working on fuel-related components requires following all fire safety precautions and making sure that all fuel liquid and vapor openings remain sealed during work through caps or tapes.

Yes, the fuel tank filler pipe hose can be serviced separately.

Avoid smoking or open flames near fuel-related components due to the presence of highly flammable mixtures. Protect all liquid and vapor fuel openings with caps or tape to prevent contamination, removing these protections before installation.
