Ive got a 1990 KR Corrado and Its had the matrix hose modification where the valve has been put in, but the small hose with an upwards bend on it has split. VW dont list or make this hose anymore. Any ideas what I could use instead? Or shall I just get a hose made up? Ive tried taping it up and some k-seal but its managing to leak out still, so instead of keep having to top it up, ive gotta replace it. Any ideas and help would be much appreciated.
