This is the by far the best hose I have found for the fuel fill pipe.
Over the life of my Suburban, previous hoses would rot a year later.
Like I said earlier, I get this hose from an industrial hose supply house. (They specialize in making custom hydraulic hose and fittings).
I would check around the industrial section of where you live, and look for a shop that supplies hose to the fork lift and big rig community.
Just in case you do not have a shop that can get this stuff for you, I am sure if you called the place I go to and talk to them about sending you a section of this stuff I am sure they would.

BTW: These guys custom made my front brake lines for me to.
They salvage the fitting if they can't get it, and in my case no one sold the fitting by itself.
I had them make longer than stock hose, since my burb is lifted and it is the original drum brake D44.
