  Q: How to Service a Fuel Tank and Replace Its Rubber Seal on Jeep Commander?

  A:

  During maintenance of the Fuel Pump module, you should always fit a fresh rubber gasket (seal). First, apply a new seal (gasket) and put the fuel pump module in the hole in the fuel tank. After that, fit the lockring (5) to the top of the fuel pump module and turn the module until the embossed arrow on the lockring lines up with the center mark to stop the fuel line from hitting the side walls of the tank, aligning the fuel fitting towards the driver's side. Hold the frame and use Lockring Remover/Installer 9340 (3) to secure the lockring, then use a 1/2 inch drive breaker (1) to tighten it clockwise until the seven notches are fitted. After that, secure the fuel tank into place.

  Q: How to Maintain and Repair a Fuel Tank on Jeep Commander?

  A:

  Draining and taking out the fuel tank should be the first step, since the fuel system stays pressurized all the time. Making note of the orientation of the Fuel Pump module will be easier by using the indexing arrow at the top of the module. Attach the Lockring Remover/Installer 9340 to the notches on the outside of the lockring. Add a 1/2 inch drive breaker bar to the tool and turn it counter-clockwise until you can pull the lockring off which raises the module by a small amount. Make sure you do not bend the float arm as you remove the module from the fuel tank. Never forget to replace the rubber seal when doing an installation. Put the fuel pump module and the new seal into the opening of the tank, then set the lockring on top of the module. Place the embossed arrow on the module facing the center mark to make certain the fuel fitting is pointing towards the driver and so it does not touch the side of the tank as the module moves. Attach the Lockring Remover/Installer 9340 to the lockring, put the 1/2 inch drive breaker bar in place and turn the lockring clockwise until you've engaged all seven notches.
