Not on my Bonnie, but I did have that problem on my Blazer. The sending unit and gasket were the problem. I was on my way up to Mississauga (sp?) for a weekend and I stopped to get gas (Canadian gas is expensive, BTW). As I filled the gas (using the locking devise on the nosel) I walked around to wash the windshield, check oil, etc. When I went back around to the pump, gas was everywhere, the nosel didn't shut off, and I owed $40 US!
It was an expensive repair, too.
There are other things that may be wrong. For example, rusted tank (holes), ruptured line, etc.
