I have the low fuel sensor kit from Kitfox and the other day it came on after a long climb. During descent it went out again and I consulted with John and did some troubleshooting. I found that the fuel line that was zip tied to the cross members behind the seat had slid down and caused a kink at the attachment of the left wing line to the collector tank. Didn't think about the line ever sagging since it is fairly stiff and zip tied tightly to the frame. Hope to show this and prevent anyone else from having the same problem. Without the low fuel sensor I would have never noticed until I ran out of gas.
Here are the before and after pics. I used waxed lacing cord to tie it up to the frame on the side and above to keep it from ever going down again.
