  Q: How to Properly Address Issues with the Fuel Filler Hose on a Mercury Mountaineer?

  A:

  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.

  Q: What are the safety precautions and steps involved in servicing the fuel filler hose on Mercury Mountaineer?

  A:

  The fuel filler hose service must include proper safety protocols because highly flammable mixtures exist near all fuel components. Vehicle fuel maintenance requires you to both restrain from smoking and ignore fire along with careful handling of fuels to defend against fires that might occur due to hot car components. Empty the fuel tank as the first step. The fuel tank filler pipe hose requires no removal of the piping to service it because technicians can loosen the fuel tank clamp to disconnect the hose. When installing the hose maintain a tightness of 3 Nm which equals 27 lb-in. Open the fuel tank filler cap if necessary then remove the three bolts before tightening them to 1 Nm (9 lb-in) at reinstallation. To service the fuel filler doors of Explorer and Mountaineer vehicles owners should push down the two tabs located on the pockets of the fuel vent. Owners of late Explorer/Mountaineer vehicles need to take off the fuel tank filler pipe upper retainer. Detach the fuel vapor tube of the filler pipe from the sensor and the rear axle vent hose as well as the dust separator hose. The last step involves removing the assembly fuel tank filler pipe bolt with a torque setting at 15 Nm (11 lb-ft) and following the reverse remove sequence to complete the service process.
