Fuel spill prevention valve

An apparatus for preventing a fuel spill from a plural container fuel storage system having an interconnecting fluid conduit in the event the conduit is ruptured, the apparatus including at least two valving arrangements one for connecting each end of said fluid conduit to a different one of said fuel containers, each valving arrangement comprising:

• (a) an exterior valving member having a bias means urging the valving member closed, the exterior member adapted at a first end for connecting in fluid communication with the fluid conduit and at a second, opposite end for being affixed to the exterior of a said container;
• (b) an interior valving member having a bias means urging the valving member closed and adapted for being affixed in mating arrangement and in fluid communication with the exterior valving member, the interior valving member being in fluid communication at an end opposite its affixed end with the interior of the container;
• (c) a flow control rod means engaging the valving members and opposing the bias means to prevent the valve members from closing so that upon fracturing the exterior member, the rod means releases the valving means to permit the bias means to close the valving members and prevent fluid communication through the valving members, the flow control rod comprising a pair of aligned non-frangible rods each extending centrally from a different one of the valving members to form a clearence space, each rod having an opposed tapered tip and an interposed, central member seating against the opposed tapered tips but not surrounding non-tapered portions of the rods.
