This is the setup I built for my FJ. A 12 gallon Moeller Topside tank and a Holley Marine grade pump. I was powering the pump with a "battery in a bag" setup, but I have since ran a aux power plug to the roof rack. When I am done with the trip, I pump any remaining gas into the truck and put this setup back on the shelf. I keep 4ft of hose in a double ziplock bag that I just connect to the pump valve and put the other end in the tank filler. When done, simply coil the hose back up, reseal and move on. No fumes in the truck, etc. The tank, being for marine use has a vent and flame arrestor as well.
