Ok,.. I've got a 30 year old CB550 in the garage with two fuel lines. 25 years ago the end of one line got damaged prying it off the petcock, and of course it was too short to clip the bad end off. That started a 25 year search for a fuel line that works. I've tried everything including braided and clear vinyl which gets hard and yellow real fast. I've tried automotive fuel line,.. too fat to fit between carbs. Urethane hose like everyone sells in colors,.. took longer but still got rock hard.
I even researched and found something called Tygothane and they make a hose specifically for petroleum fuels. I called the company and he assured me it didn't use plasticizers and wouldn't get hard. Its industrial stuff so I had to buy 25 feet for $75.00 Well a few years sitting in the box and it started to decompose. It looked like it was sweating and it felt real sticky so I threw it out. Ive had 10 different hoses on there, and the original one still left is in decent shape after 30 years.
Yes I tried ordering a replacement from Honda but its discontinued!!!!!!!!!!!! I got persistant and found a sheet from a dealer parts book that shows the numbering system to order bulk hoses. I put together some part numbers but the local dealer says they won't go through the computer.
Now I'm stuck looking for some newer Honda that uses a 5.5 mm ID hose 300mm or longer. Anyone know of a bike that uses a long hose, or know of something that will last more than a year or two??
