  • Removable fuel tank for diesel engines
    Patent number: 7021344
    Abstract: A method for preventing use of an unapproved fuel in a diesel engine uses a fuel tank that does not have a conventional fueling opening and has a puncturable fitting for connection to fuel lines of the engine. The engine fuel lines terminate in a mount that has fangs adapted for puncturing the fuel tank fitting. The tank is against the mount so that the fangs puncture the fitting to allow fuel to flow from the tank to the fuel line. Since the tank does not have a fuel filling opening, it cannot be refilled without special equipment and must be removed from the engine for refilling.
