here is link to part I mentioned would be in or around where wiperblades and similar parts are in any car shop:
I looked at the link but did not find specs on what kind of material that is made of. If metal may be OK for gas, but some plastics will melt or soften.
On an associated, but separate issue I even had some clear fuel tubing from an auto parts store soften and the clamp loosen and leak. I rather the neoprene rubber hose that is marine fuel line and seals with those cable clamps real good.
On a search I found this from an auto parts place so maybe in your town can get local also.
