Cool that you found a good used valve.

Was just thinking of a possible alternative that could be sourced on a
weekend during a tank reseal. The grommet is NLA so Van cafe must have
sourced a grommet from somewhere. It's one of those parts a newb or even a
more experienced Vanagon wrencher could oversee in their parts estimate and
suddenly need asap.
