lol...
ah ha !
easy mistake to make if you havn't done it before, or not generally
doing this test now and then.
Things are not always clear in that book anyway. < really ...it's very
'german' ....and there are mistakes in it for sure.
  try following what they say for pressure testing a waterboxer pressure
cap - they show you testing a diesel vanagon one, and mention an adapter
.....if you look up that adapter, it's for a diesel vanagon old style
conventional cap, totally different than the blue waterboxer cap - so
don't put 'absolute' faith in that book - combine what they say with
logic and cleverness.
Anything that was originally done in german ...there is always a bit of
subtle oddness.   Written by engineer-type minds ...falls short in the
real world now and then.

and now you know..
the point is to remove the vacuum line to the FP pressure regulator for
the test.
I only find a bad FP regulator ...not even once a year..
like only one out of 50  ( or more  ) 1.9 wbxr vanagons.
It's a test that needs to be done ..plus it's very easy to do.

lol - I think you like the attention - it's cute.
'baltherskite' ..is that Yiddish ?
