I am looking for some fuel hose for my 1993 300D, 2.5L.

The hose I need is under the hood, and is used from the metal fuel supply pipe to the primary fuel filter and pump and on to the injection pump.

The existing hose measures about 13mm OD and the supply pipe ID measures to be about 7.6mm.

I can get 7mm ID and 8mm ID from my parts store. One might be too small and the other too big. What size do you guys use?
