[Karl Mielenhausen _/)]

Joe,

This was addressed in the May 2009 Mainsheet.

BTW, you can find this by going to the C320IA website and searching for  
"fuel gauge".
Of course you need to be a dues-paying member and logged-in to access much  
of the content.
Why would you NOT want to support the association?
Best $24 you could spend in boating!!!
