This fuel filler grommet mounts in the fuel tank and seals the fuel filler neck where it enters the tank.

It's 70mm od and 38mm id, an odd size which fits only very early models of Vanagon. This is also used when converting from an early metal filler neck to a later plastic version.  Additionally, we have seen this grommet on some singlecab and doka pickups.

Please measure the diameter of the filler neck where it mounts in your gas tank to confirm the size you need.
