When I was replacing the fuel hoses, I also replaced the filler hose. It was still in one piece after removal but it was very weak with a lot of cracks. Definitely not safe!
Of course ‘while you are there’ I cleaned up the ubiquitous overspray. Somewhere in the car’s life someone sprayed black everywhere instead of cleanig the dirt off. The new hose is very stiff and required some green soap to encourage it over the fuel tank and filler pipe ends. It should be good for another 10 or 15 years.
