I wouldn't think there would be too much of a difference between the years.... I used a shop vac hose kit to make mine.... I think its about 2+ inches. I did have to trim the side piece that pops of and then cut the hole in the little piece that comes off on the front. I did have one that was 1.5" and I managed to get it between the plastic and gas tank but my plastic kept popping out around the gas tank so thats why I changed it
