I am building a 65 chevy 1/2 ton truck. I pulled the stock gas tank from the cab and I do not want to put a tank in the frame so I am looking at putting a fuel cell in the truck box. My question is can a guy put a fuel cell in the open and be exposed to the weather/sun? or will it get to hot on really hot days. I kind of wanted to go with a polished one but would consider a black or the red one. I think of the utility trucks that drive around and their tanks are white - it must be to try and keep things cooler - right? Please let me know if it is smart to do or not. Thanks for reading.
