Recently, I've been brimming my tank to work out my MPG more accurately. But my car is sometimes feeling less than smooth. This may be unrelated as it occurred after a recent service.
But, I was wondering if the diesel tank has a breather to it. If not then it may be creating a vacuum. I noticed that when I filled a tank part full it seemed to run better. It's all very subjective I realise and could be all sorts of things but is the tank vented in any way to avoid vacuum?
Thanks in anticipation
