I have a pair in this position and approved for test. They did not require it
to be visible right down to the bottom so it can be outside the tunnel. The
scale expansion due to the small tank section near the bottom (and only half
of it) means that only the last 5 litres is not visible. There is a small
error still on the ground (10mm level change) which means different things
according to which of the 3 scale rates you are on, but it is far superior to
the original. By returning their tops directly to the tank, the dorsal vent
becomes available for the pressure (ASI) fuel gauge in the headrest end,
overcoming the PFA's objection to fuel vapour in the case of the that
instrument.
