Upgrade your fuel system effortlessly with our Diesel Auxiliary Fuel Tank, designed to meet all FHWA (Federal Highway Administration) requirements for non side-mounted fuel tanks. We've taken the guesswork out of the purchase and installation process by manufacturing our diesel fuel tanks specifically for seamless integration with the included Fuel Shotz installation kit.

This diesel FUEL SHOTZ installation kit can be installed in less than an hour. The unique system connects the auxiliary tank to the factory tank via the factory filler. The auxiliary tank keeps the factory tank full. When the auxiliary tank is empty your factory fuel gauge will move off the full mark. The system installs quickly and easily. No wires or switches to install. The system has rollover protection on the tank and on the factory fill neck adapter. Detailed Instructions are supplied with the Fuel Shotz installation kit.
