If you own a 2000 VW Jetta, you may need to replace the fuel filler neck at some point. This is a process that involves opening the fuel filler door, removing the bolts that connect the tank retaining straps to the underside of the vehicle's body, and lowering the tank. You will also need to disconnect the vent pipe from the fitting on the filler neck and remove the screw that connects the ground strap to the filler neck. This process is similar for the VW Jetta GL and GLS models from 1999-2005, and the VW Jetta Wolfsburg from 1999. It is important to note that you will be working around raw fuel, so caution should be exercised.

Open all the doors and rear hatch and make sure the area in which you work is well ventilated. Fuel vapours can be very dangerous. I also recommend wearing fuel-resistant gloves and a carbon filter mask for protection. |

How to locate the fuel tank
To locate the fuel tank in a 2000 VW Jetta, you will need to open the fuel filler door. You can do this by peeling the rubber seal away from the vehicle's body. Once you have done this, you will be able to see the bolts that connect the tank retaining straps to the underside of the vehicle's body.
To access the fuel tank, you will need to remove these bolts and begin to slowly lower the tank. You will also need to disconnect the vent pipe from the fitting on the filler neck as it becomes exposed. You will then need to remove the screw that connects the ground strap to the filler neck.
Once you have done this, you can lower the tank and slide it out from underneath the vehicle. You should now be able to see the fuel tank.
Please note that you may need an assistant to help you steady the tank while you remove the retaining straps.
