Abstract
A failed nozzle relief (FNR) valve has a resetting mechanism that resets the valve when a filler cap is replaced over the filler cup. The FNR valve has an annular seal that surrounds a filler neck opening. The annular seal seats against a ring having at least one aperture that creates an alternative fluid flow path. During a failed nozzle shutoff condition, the annular seal separates from the ring, opening the aperture to allow fluid to flow through it. The FNR valve also has a reset lever that is pressed downward when the filler cap is replaced, thereby forcing the seal back against the ring.
