The plastic tank manufacturer also has to either chlorinate or fluorinate the plastic to retard permeation, and both processes can be highly toxic if mishandled. This represents additional OSHA requirements, which add to the cost of the tank.

So it's either polyethylene or Ceramic, and I would go with ceramic.

Answer 7

Poly tanks are solid, they do no longer rust, and that they are versatile. even nonetheless over the years they're going to crack and leak. I certainly have a poly gasoline cellular in my YJ and after 4 years it cracked approximately 8 inches long and a million inch extensive.

Answer 9

Ceramic is porous i think

Answer 10

polyethylene
