Assembled fuel hose with proper cohline hose and sleeves. Roger at 928s r us only had 3 the right size left, and cohline is not supplying them anymore. Is it a coincidence that cohline stopped offering them publically when porsche started selling these lines new again with cohline fittings? In any case, the barbed ends are available from belmetric.So, if you want to make your own hoses like i did, drill the end fittings out from the inside of your existing hoses in order to harvest the sleeves.
