Interesting experience. I think some tank materials would resist that. Before I get to the tank part of my project I'd like to incorporate the most fuel-indestructible tanks short of metal. (I have Diehl skins to use)
Also wonder then what that absorbed moisture does to other performances of the fuel such as vapor lock, fuel efficiency, and octane?
