This vacuum hose has a specific internal diameter of 3.5 mm and is intended for limited use only. It should therefore only be used for applications specified by Volkswagen, which, if available, are also shown in the exploded views.
If you use the hose where a diameter of 4 mm or more is required, it will overstretch and open prematurely.
This hose is identical to the original on the outside, with a textile braid on the outside. On the inside, this hose meets all the modern requirements needed for today's fuel.
