Fuel tank pump issue, level sender issue

The right will drop to about 1.5L when the left is about 27L. The left will drop to zero then the right will drop to zero. At that point about 3.6L left but the internal reading will be zero and DTE will stay zero.

There's not much swapped over in the LHD/RHD versions - just the driver controls mostly. The signal and wiper stalks aren't even swapped over for the RHD (good thing I have an auto, or changing gear and operating the signals while cornering, all with the left hand, would be a mission!).

And the tank is identical on both LHD/RHD versions of the e53. If you are referring to the (Russian?) video - maybe the car is an e39 - not sure.

What I do know is my own RHD e53 operates exactly as per all your research indicates for the LHD versions, in terms of tanks emptying rates etc.

Well, almost exactly. It seems that when pumping diesel fuel the electic fuel pumps last a lot longer and the o-rings don't seem to swell or distort as badly.
