ABSTRACT:
An extension for the fill port of a fuel tank. The fuel tank has a wall and a fill port. The extension comprises a tube having an axis, an innermost end, and an outermost end. The tube is axially movable in the fill port with its innermost end inside the fuel tank and its outermost end outside of the tank and adapted to be closed by a closure. A peripheral flexible diaphragm has an inner and outer periphery, the diaphragm being imperforated between its peripheries. The outer periphery is sealingly attached to the wall and the inner periphery is sealingly attached to the tube adjacent to its outermost end so that the diaphragm makes a fluid sealing barrier between the tank and the tube to prevent escape of fluid from the fill port except through the tube. The diaphragm is shaped so as to flex and thereby enable the tube to move axially from the retracted to an extended position relative to the fill port. Desirably a releasable latch is provided to hold the tube in its extended position and torsion means is provided to hold the latch engaged.
