Shortly after dropping my fuel tank to replace each and every fuel line all
the way to the injectors my gauge is not nearly as accurate. I checked all of
the connections and terminals and all were clean and in good shape. I'm sure
that the gauge works off of resistance so I also need to find this connection
 and a bad ground in the circuit is bound to be suspect. So do I need to drop
the  tank again to check this ground point? Not sure based on Neil's photo.
Mine is a  90 Westy BTW. Thanks fellow Vanagonauts!

Ok.

So P 97.127  in Bentley shows the fuel sender ground at "29" which is
"near Digifant  control unit".  A misprint? Or is my Vanagon
"geography"  off?

Here's a pic of my '81. I moved the fuel sender ground wire  forward
when I had the gas tank out, but am almost certain it's the  ground
wire in  question.

Is  this near where you found your wire  Phil?
