Hi gang,

Sorry for the noobish question, but I was just reading another post and have to ask. Since I bought my '95 E300D about 4 months ago, it has regularly made a suction sound - like breaking a vacuum seal - when I undo the fuel cap to fill up. Being new to MB and diesels, I thought this was normal, but it appears as if it is not. Others seem to suggest that there is a fuel tank vent that can get clogged and create this situation and subsequently affect fuel flow. Can someone confirm this for me? Also, anyone know where to find the vent?? Thanks in advance!

- Mark
