No fuel hose is "fit and forget" as other people will advertise as silly prices. This is the original style braided fuel hose. Tried and tested on our own vehicles over the last few years. Fuel is changing, with added ethanol this is clearly causing issues, and worrying people too. We have got the Codan bio safe fuel hose listed too for added peace of mind. However, we always advise checking the fuel hose every 6 months, and for the price, we change it every year at each service just to be sure. But we left this on a few vehicles for a couple of years, and there's no sign or perishing.
