Where I’m working on the old load again: For some time now (1-2 years?) my tank watch no longer shows really full, although definitely is full. Say: Pointer stands max. on 65L and drops after some KM then quickly to 60L. Reserve indicator however comes suitable after approx. 55L consumption. What is that now again? No human has fumbled about it. And: since also for a while it smells in the moose for fuel, when I have filled. Sometimes violently, sometimes not so bad – but n ervig. I always only fill up to the “knack”. There is also nothing over or out … Tank ventilation ? I have never been there. Or what else ?
