I was given one of these to try out and hadnt ever heard of it before. I did a little Google-ing and it seems pretty cool. Didnt know if anybody had ever used a Tank Snake or if they had, how it worked. Heres the link: Tank Snake | Products |*B3C Fuel Solutions
Anybody have anything on these products? There arent any directions but it has fishing line attached to one end and a loop to tie off outside of the fuel tank for extraction (Im guessing). Apparently it turns blue when absorbing water over time.
