Dear Annie,

There's a rather complicated setup to maximize the tank capacity by
transferring the headspace to two little plastic tanks in the fender
wells.  This involves a bunch of vulnerable stuff.  If you've got
Bentley, look at 20.26.  If you haven't got it, do get one even
though they're expensive.  It will no doubt save you money and
trouble even if you don't do your own work.

The other major possibility involves the saddle in the tank,
originally there for the heating duct in the air-cooled models.  Wet
leaves and trash can accumulate there and rust through the tank top.

VanAgain, Bus Depot, no doubt others sell kits of all the little bits
for the venting system.  People with small hands and excellent
spatial perception have been known to replace this stuff without
dropping the tank, but in general that's not realistic.  The tank
will be much easier to handle and less likely to crush you like a bug
if it's about empty -- 16 gallons of fuel weighs about 110 lb.

Yours,
David
