All that said, I can't tell how they seal just yet since I have not put more than 5 gallons in the tank, but I have NO fuel odor which is a good sign.
Good to know, once its time to get the tank in hopefully you have more details The new design does seem better. Having had a fire before in another car I would love to not have this again!
