I wish I had realized this list existed a couple of years ago.  I must
not be spending enough time playing on the computer.  I recently sold my
'81 Vanagon after almost 10 years with it and bought an '89 GL.  The '81
had problems off and on with the fuel supply- coughing and an almost
complete loss of power that I finally determined must be sediment in the
tank when I discovered that (carefully) blowing into the line from the
tank would solve all my problems.

Now with the 89 I have had similar problems about 3 times.  The engine
will be running perfectly and then all the sudden I'll have a huge loss
of power followed by surges and it all feels like the van is starved for
fuel (or perhaps not running on all 4 cylinders?) .  The first two times
it cleared up within a couple of minutes and the third it lasted
longer.

The flow out of the tank seems normal and I put on a new fuel filter but
it hasn't solved the problem.  It doesn't seem like a clogged fuel
injector or bad fuel pump would come and go sporadically like this.  I
would greatly appreciate whatever advice anyone might be able to give.
