I have developed a small fuel leak from the plastic tank of my B7100. I haven't had a chance to check it to the cause but was looking for direction on what would be a good product to repair it with, I expect to find a small hole or seam leak, I was thinking a two part epoxy ... I have checked into a new tank but see it listed on one site as discontinued and then available on another, so I'm unsure about the availability now till I get a chance to call about it. Thanks for any help.
