The neck (top half of the hose) has the fittings at the top where the hose at the gas station fits in. It also has a connection for the vapor line, so it would be difficult to make a good replacement. The lower section is basically just an elbow with clamps. The hardest part is that you need to find a hose material in that size that is fuel resistant, gasoline will quickly destroy standard radiator hose. An aluminum elbow with some silicone couplers as somebody else suggested would probably work for the lower hose. But if the OEM replacement is still available why not get one while you can and have something that fits perfect, doesn't require sourcing hose/fabricating, and will last for another 18 years?
