Replacing the fuel filler neck on a 2000 VW Jetta involves a number of steps. First, you need to park your vehicle on a flat, hard surface and make sure the transmission is in park (for automatics) or in 1st gear (for manuals). Then, open the fuel door to access the fuel filler neck. You will need to remove the mounting screws or bolts attached to the cutaway, as well as the fuel filler cap cable. Next, locate the fuel tank and lower it using a transmission jack or similar. Disconnect the harness from the connector and feel for a harness attached to the tank. Finally, lower the fuel tank more to reach the vent hose and remove the clamp and small vent hose.
