To free up the room behind the seat, I've been considering building (ok, having built) a box in the bed, just large enough to hold the gas tank (standing upright the way it is behind the seat), with a lift up lid to access the filler spout and a locking gas cap for peace of mind. Think of a "between the bed rails" diamond plate toolbox, 8.5" deep by 65" wide by 18" tall, standing upright. Minimal work to re-route the fuel lines and electrical, Plus you get to keep your sending unit, you only lose 8.5" of bed space, and my spare can stay hanging underneath out of the way. I would leave the original filler neck in the cab, and just cap it off inside, to retain the original look of my truck.

Thoughts?

You may find that your tank will get water inside from condensation. If the tank is cool and the sun comes out, it will warm the outside of the tank causing condensation on the inside. If it was under the truck, your bed would block the sun. Also, how are you going to mount it? Be sure to isolate it from metal to metal contact. Hope I helped.

 

Ken...

Not trying to be a smart*ss, but help me out.

Inside the cab in the hot sun, or inside the box in the hot sun... inside the cab it's attached directly to the metal back wall, inside the box it would be attached to the back metal wall. What's the difference?

FYI I was going to use whatever mounts are inside the cab inside the box, so it would be mounted the same way... anticipated needing some rubber bumpers to insulate the tank... appreciate any feedback.

Thanks!

No offense taken or implied. Just trying to help consider all of the angles. The metal to metal contact I was refering to relates more to exposure and rust than anything, the tank doesn't get wet in the cab.
