While the Transfer Flow is a well known tank replacement, it is made of steel and very heavy and prone to rust after a few years. If I was looking at a replacement tank for a diesel, it would be the Titan plastic tank, hands down. No rust, light, takes a hit and doesn't break, and easier to install. If titan made one for a gas rig, I would have installed it years ago. Just sayin'.
