There are fuel expansion tanks above and on both sides of my
84 vanagon tank.  On each side there is a rubber grommet with
a plastic Y-tube in it.  One branch of the Y goes to the expansion
tank on that side, and the other branches connect to each other via
tubing.  One of my Y thingies just came apart spontaneously while
I was filling the tank.  When I got down to fixing it, I found
the other one was cracked as were the gaskets.  I have long arms,
and gained access by removing the front wheels and of course blocking
up the front end well.  Removal of the tank was NOT necessary.  But
I tried that first.  It was quite heavy, even empty, and I had no jacks at
the time to help with reinstallation.  Try the wheel-removal thing first
unless you have other concerns that really require tank removal.

I can't remember if I jammed the new Y thingie through the new gasket
with the gasket installed on the tank, or whether I first put the gasket on
the Y thingie.  Whichever it was, it was pretty tight getting both pieces
in place.  Patience and fumbling.

Oh yeah....... try to clean all the sand from the whole area to keep it out
your hair and eyes and gas tank.... so do the cleaning BEFORE you have
the old parts removed and the gaping holes ready to catch the debris.
