Check these people. http://www.plews-edelmann.com/brochure.cfm?brochure=1876&location_id=2516 Brochure does not list the part number, but I have an old carton from them that is probably what you need that came from Edelmann-stant. Edelmann number 3200ST is 1/8 diameter, copper plated steel tubing, made for oil pressure senders, etc. Bends easily, durable steel tubing. Don't use copper and don't use plastic. I bought it 20+ years ago. Maybe they still carry it maybe not.
