I found in a breakers yard a Peugeot that had coiled plastic strips along the length of some fuel pipe, only noticed as I walked past so I removed it by unwinding it, it was about 3 feet long and I used it on my Rover v8 around fuel pipes and breather pipes. When uncoiled it looked like a long spring. Where you would actually buy this or what it's even called I have no idea. Just did a google search and found bugger all.
