Hi, the other day I was filling my Tigon tank and the Seal in the Top Cap ripped and now the Tank leaks. The Seal had separated away from the fill port a few weeks ago but I just moved it back in place with a toothpick however the last time I forgot to move it out of the way before I closed the cap and ripped it. The Tank will not work now so I need either a new fill port seal and a way to take apart the Top Cap to replace it or I need a new Top Cap. I do not need the rest of The Tank. Where can I get one? I've included a picture of the leaking Tank. Thank You for any help you can provide.
