Auxiliary and Transfer Fuel Tanks
A collection of auxiliary/transfer fuel tanks I've found around on the web. When possible, I have included a link to where I originally found it, as well as who the owner/creator was. This is just so that people can find a greater amount of information about these tanks all in one place, and is not meant to replace any of the owner's original write-ups. The heading before each set of images - when possible - is a link to the original source.
Auxiliary vs Transfer
An Auxiliary tank is generally hooked into an active fuel system.
A Transfer tank is generally only used to re-fill the OEM tank.
Gravity vs Fuel Pump
I've read the rumor many places that gravity-feeding tanks are illegal. I have not yet found any law in any state that restricts the use of a gravity-feeding tank from filling the OEM tank (e.g., as a transfer tank does). The only laws I have been made aware of make it illegal to have a gravity-feeding tank that is directly hooked into the fuel system. Gravity fed tanks have less area of failure, and are cheaper to manufacture, purchase, and install. My personal tank in my Ram 2500 is gravity fed. I do not currently know enough about fuel pump systems to speak about their pros nor cons.
