Thanks for the warning JB. I will take a closer look at my 12 year old plastic tank that I have been using meth in. I don’t dought there could be a problem, yet a few other things could be mentioned. I dought you have any idea of what other than pure meth fuel was in that tank over the years of it’s life. I am sure that plastic tanks are still safe for methenol use yet your point of checking mine and others tanks for brittleness needs to be done. Meth should not be left in either aluminum or plastic tank that is ventelated like our kart tanks are. Yet I am guilty of this bad practice, and do know that my tank hasn’t had just pure meth in it through out it’s life.:)
Maybe there is differant ratings on these plastic tanks that I am not aware of?
