new gas tank for 2009 Te310

How much and how hard would it be to replace my gas tank on my 2009 Te 310. I rode it last summer in 110 degree weather and the tank expanded or warped and the plastic body parts don't fit under the other plastic body parts because of it. Are there any gas tanks out there that don't warp? Is it a common problem for the 2009 Te 310?

Black tanks more than white.

Part of the issue may be the pressure valve in the line. Take it out in the heat so the pressure is less. Might spill a little gas now and then but....
