If you are planning on running a fuel cell where the spare tire is then you have some things to consider. I peronally wouldn't build a cell for my son if i've never built one before. I would consider a fuel cell from Race Safe as it has an internal bladder that will contain the fuel in the event of an accident. The other thing to consider is to have the fuel pick up in the top of the tank instead of the back portion of the tank where it could be in harms way.
Other suggestions would be to make sure that it is narrow enough to allow room for the exhaust to pass by the sides of the tank and not obstruct the rear suspension. You have to leave room for heat shields also. There isn't alot of room back there and we were only able to figure out 10 - 13 gallon tank if we made the exhaust exit out the back. This is one of the reason we moved the exhaust exits to the front of the wheels. We also added a round 1/4" tube to protect the tank in the event of an accident. None of which would help if I get hit hard enough.
The other option you may want to consider is get a tank from a 2wd Jimmy as they fit between the frame rails and have a pump and pick up already mounted. It's a pretty straighnt forward install and it has OEM saftey.
