Fuel cells exposed to the weather/sun?

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.

First, welcome to CHR. It's good to have you here posing your questions. As long as you have the tank properly vented you'll be OK with an exposed tank, IMO. Your choice of polished is ideal, because that will reflect the maximum amount of heat possible. Black would be the worst choice if you're concerned with heat.

My fuel cell is attached to my frame and because I have a tilt bed, I made a cover for the fuel cell with an aluminum pop-up door for fueling. Here is one picture, but I can provide more when I get home.

would you quit screwing around and finish that truck ! .......................... :)

i'm putting an s10 tank in a aluminum diamond plat tool box in the bed. i plan to lizard skin the inside pretty heavy . good vent but will run a plastic filter on the end .

Like Roger said, proper ventalation is the key. Those cheap plastic ones will swell up enormously without a good vent. Also make sure whatever vent you use has an anti-roll over protection ball in it just in case.

Thanks so much to all of you guys for your impute. I am feeling better about doing the exposed fuel cell now.

Good luck on the project!

i will be using an s10 tank in my 54. i will set it in a diamond plate tool box .

If the truck turns out as good as the chassis looks, you will have a helluva nice ride.
