----My 68 Corsican (serial # 2) has an inch and 7/8 fill hose. I found it difficult to buy only as much as I needed (3 feet) so ended up having to buy 10 feet. If anyone needs any of the remaining Coast Guard approved 1 7/8 red stripe filler hose give me a call and Ill sell you as much as you need...….Bill S, 810-420-0431
