As others have noted it is part of the design for that tube to run above the
tank. It is there for venting and providing a vapor path/collection for the
vapor recovery system. That system is the path for air to go in as the
engine sucks the fuel out. While you never had or noticed a problem I have
seen amazing failures happen to the system including fuel tanks getting
sucked in from the carbon canisters failing and blocking the inlet to
gasoline somehow pushing out of that canister and pouring fuel into the
frame rails. I still haven't figured that one out! Anyway, one thing I
learned is that VW doesn't do much of anything with a purpose and when stuff
is left out there can be a consequence.

As I have said before, I see no reason that the crossover tube needs to be
straight and rigid. It can just as well be a piece of hose that is long
enough to loop around and go *under* shift linkage or coolant pipes or
whatever.
You need hose of the right size, rated for gasoline, of course. It will
likely be too stiff to comfortably go directly across and down into the
depression completely. If you turn the fittings where it attaches about 30
or 40 degrees, you can direct the hose forward enough that it will go under
the misc. obstructions without much stress. This can all be adjusted and
assembled on the top of the tank before installation in the van. As you
mount the tank you can look above it from the back and check that the hose
is not rubbing against the e-brake cable or shift linkage, etc. Adjust by
poking with stick if needed.
My '91 GL has had this setup for about 4 or 5 years now with no problem.
Also, if you're smarter than me, you will replace those plastic fittings
*before* they crack from old age. :-)
