Up for sale is 1 foot of 3.5mm id braided diesel fuel return or "injector" hose made by Continental Germany. This is what came on your diesel Mercedes, Volvo, Audi or VW from the factory and is the only suitable replacement for these cars. I have personally used this stuff for the last 15 years with no issues. In the automotive service world Ive literally seen every other kind of hose used for this application and no others compare. The yellow stripe that you see in the pic shows you that it is durable enough for diesel fuel. This also works great as a vacuum hose, motorcycle fuel hose, etc.
