If the overflow system has never been renewed, it is time to do it. It
takes a little work and some fuel lines and new grommets. It can be a pita
kind of job for an impatient patient.
The tank does not have to be fully taken out but dropped at the rear side.

could be the large grommet sealing the filler tube to the tank, the
connections on the filler tube itself (adjacent to the body, inthe wheel
well), the small hose coming off the filler tube or it could be one of the 3
(?) grommets in the top of the tank (those grommets which seal the tubes to
the expansion tanks).
You might be able to see a leak in the filler assembly, the grommets on the
top of the tank are harder to see when tank in van. You can reach in and
feel them with your hand. Chances are it is the harder to see grommets. If I
was you I'd plan on dropping the tank and replacing them.
