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?
