This might help...
Oversize Tank - Replaces the OEM Tank
Aux Tank - In addition to the OEM Tank Can be frame mounted or bed mounted.
There are many ways to get the fuel from these tanks to the engine.
Transfer Tank - These are mostly bed mounted however there are some that can be frame mounted. You must manually transfer the fuel from these tanks. The advantage is that you can also pump to another vehicle if necessary. You see these a lot down on the farm.
I have seen folks tie these into the filler neck for their main tank and use an electric pump switched in the cab to make the transfer. They use their fuel gauge to view the progress. Some aux tanks have a similar set up but there is a overflow prevention shutoff built into the replacement section of the filler neck.
Most of the folks with 3/4 ton Crew Cab Short beds look for these to extend their range however they are pushing the GVWR numbers if they have more than an ultra light.
