Good luck and let us know. Also good to know that there are special seals that can only be exposed to DEF... Not that I plan on putting anything else in the tank but DEF.
Although only knowing a little bit about chemistry, it is hard to believe that a seal can survive DEF, but not diesel fuel. Biodiesel is corrosive, so I could see Bio eating through a seal.
