<p>A high-pressure fuel hose (64) for disposition between a tubular stem (30) on a fluid connector (28) on a canister (12) in a fuel tank and a tubular stem (60) on a fluid connector (52) on a cover (36) for the fuel tank spaced from the canister (12). Each of the tubular stems (30,60) has a fir-tree barb (32A,32B,62A,62B) thereon and the high-pressure hose (64) includes a convoluted flexible body (74) and a pair of relatively stiff cylindrical ends (78A,78B), each of which has a pair of annular inside beads (86A,86B) and three annular outside beads (88A,88B,88C) between the convoluted body (74) and the inside beads (86A,86B). When the cylindrical ends (78A,78B) are press-fitted over the fir-tree barbs (32A,32B,62A,62B) with force applied at the outside beads (88A,88B,88C), the inside beads (86A,86B) seat behind annular shoulders (84A,84B) on the barbs (32A,32B,62A,62B) for enhanced retention.</p> |
