I have a 2013 Fiat 500 lounge soft top 850. I had to have my fuel line replaced in June this year after a large fuel leak. The garage didn’t check if there was rodent damage. This time it was clearly visible after my second large fuel leak. I’ve taken pictures which clearly show bite marks all along the plastic pipe. This has been replaced today but fiat will likely backtrack on warranty as when the pipe goes back to them the damage is clear so it will be another £249! My boss also has a fiat 500 which this year had even worse rodent damage which cost over £2000. He claimed on his insurance. We both think that our staff carpark which is in the middle of a forest is where the damage has occurred. It seems that fish something or other may be used in the manufacture of the plastic which is obviously attractive to wildlife. There are several posts in the USA of this happening and not just to fiats and a suggestion was to cover with some sort of metal tubing. My garage is happy to fit it. Having seen under my car on ramps and how fragile this pipe is I’m amazed. And they’ve told me that all car fuel pipes are like this. So my question is has anyone who this may have happened to managed to find a good metal flexible pipe to cover the plastic fuel line. I can’t give up my job and I need to park in the staff carpark! It still has the sand down from my leak in june!
