How do you remove a stock gas tank from a 1964 valiant

Put the rear on jack stands. Remove the three screws from the filler neck to the quarter panel. Remove the screws from the filler neck grommet in the trunk. Remove the sending unit wire and the fuel supply hose from the sending unit. Get a floor jack under the tank. Then remove the nut holding the tank strap on. It works best with two people as you need to gently drop the tank while the person on top guides the filler neck out of the tank. Installation is the exact reverse.
