The capacity of the tank would in my opinion be approximately 65litres, then you would have the distance between the tank and the filler .
I wouldn't fancy letting mine run that low as diesels need to have their fuel pumped through when empty, plus you'd pick up all the bits at the bottom of the tank into your engine.
