Hi Richard,

In regards to your overflowing gas tank, I also had the same problem.  
The Vanagon gas tank has 4 grommets(Bentley calls them gaskets).  Two
grommets hold lines leading to your 2 expansion tanks, one grommet holds
a vent line to the top of the filler neck, and a large grommet that
holds the filler neck.  I had to drop the tank because the fuel tank
grommet that the fuel filler neck passed through had become hardened and
allowed gas to spill out when I filled the tank.  Its a pain to remove
and replace, but it should not take a good mechanic 4 hours to remove
the tank, replace all the grommets, and reinstall the tank. It took me 4
hours to do the job in my driveway.
