I've read over all the notes files, have instructions from vanagain,
and have read over the Bentley manual.  A few last questions before
having my mechanic (who works on foreign cars, but is not a VW
specialist) do the work.

1. The kit I purchased (van-cafe) and others do not include the
grommets or seals for the two expansion tanks.  Is this because they
rarely fail?  Or?
This is especially confusing since the vanagain directions note: "Also
when reinstalling the expansion tank lines remove the rubber grommet
that seals them to the tank and pop this into the tank first while you
have the tank out, then pop the lines into the tank."

2. One person I spoke with suggested that when reinstalling the
cross-over tube, it is not necessary to place this over the coolant
lines.  Every article I read on the web has it re-installed over the
coolant lines.  Does it matter?

3.  The Bentley manual noted to use a tool 2012A when removing /
re-installing the fuel gauge expansion unit.  While my mechanic does
work on VW's and other foreign cars, I would guess he does not have
this specific tool.  What are the alternatives?

4. The Bentley manual noted one should test the system for leaks using
US4487 after it is done.
   - Is this done before reinstalling the gas tank?
   - While this makes sense, I again doubt my mechanic has such a
tool.  What are the alternatives?

thanks
