Subject:      RE: what causes burping?

Hi.  Thanks to those who responded to my question.  A new fuel filter
solved the problem.  It turns out that there was a round metal filter
present (I'm not sure why I didn't see it before), but it was the wrong
filter which is maybe why I didn't recognize it.  The previous owner lived
in a part of SC where it seems that nobody had ever heard of a vanagon. 
The VW dealer in terre haute, IN told me that the filter that was in there
wasn't even for a fuel injected system.  I haven't noticed too much
difference since the filter was changed, but the burping stopped and I
made it to the east coast without any problems.  It could be that the gas
I bought was the last straw for the old filter.  Anyway, it's nice to have
the right parts. 
Thanks again for the help...........david (somewhere in the eastern time 
zone)
