I have unfortunatly holed one of my hoses (the plastic belly pan rubbed through the braid covered hose) so i took the hose to a local specialist to get one made. He say’es that they are quite a high tec construction, very flexible, high heat resistance and having crimped fittings makes them difficult to reuse on a new hose, I’ve told him to have a go, what have igot to loose. Have a look at yours, genuine replacements won’t be cheap if you cannot get one made.
