I've got a kenner 18' center console. The filler port is on the center of the console since the tank is under the console. The 2 1/2 hose is getting rotten and leaking so I need to replace it. Problem is that I have been unable to make a replacement hose be the same shape. See my attached photo. So I'm looking for any advice on how to make a new hose take on the right shape. Heating it, put sand in it to keep it from kinking or whatever. Need some ideas. So far all I've accomplished is putting a kink in a new hose and that restricts flow too much.
