I'm dealing with the same issue with my daughter's Islander (2010). You occasionally get a stinky fuel smell. Sometimes you can go for days and smell nothing. Other times I can smell it as soon as I walk out the house.
I'm installing a Motobilt/TJ tank in my JKU this spring, so I'll swap my tank for hers. While it's down, I do intend to at least understand why hers is smelling. Since I won't want to break the seal on my pump, I'll drop her tank first and steal her pump for my Motobilt tank. I'll be sure to get a new seal in anticipation...
