Abstract
A fuel tank fill tube has a telescoping valve element slidably disposed on a tubular portion thereof. The fill tube and valve element are nonmagnetic. An iron collar is secured to one end of the valve such that on insertion of a magnet carrying fuel nozzle into the fill tube, the valve is opened by magnetic forces between the collar and the magnet to permit fuel flow into the tank. The valve is urged in the closing direction by a spring.
