If youre still having issues with this. It could be the valve that opens and closes got damaged in the dirt or cleaning process, its a terrible design, i think the recall was for the earlier builds, I had it come up after hunting and passing thru some deep bug dust and creek crossing its basically created concrete, then after driving through Yellowstone during a rain storm it managed to saturate enough of it to flush it out, and it went away. Its a stupid thing we have to deal with, and expensive to replace, and a ***** to take apart to clean out. You'll know if there is something up with it when you fill up, because it will act like the tank is full and stop when your filling up before its full, really kind of a pain.
