I replaced mine in the spring. Used certified fuel hose, bendy but with metal wire on the inside so it can’t collapse. It was extremely easy. I think I had to slice it off the deck fitting, but taking it off the plastic tank was easy. Fitting it back on in reverse was a breeze. I think it was €25-30 to replace. Make sure you take it to the chandlery to get the proper stuff. And of course, new double 316 clamps.
