RMC, a generic view would consider that just because something can be displayed, should it be; particularly if there other means to alert a condition which requires action.
Guidance for designing display formats includes the importance of identifying those items which declutter the picture, both physically and mentally. The human has a great capacity to ‘see’ many things at the same time, but due to the process of perception, not to understand everything or consider the importance of each, thus the risk of subconscious mental clutter or distraction.
For a fuel tank display, a brief flicker in change of fuel quantity can distract the mind from what may be a much more important task.

The general recommendation is to follow the manufacturers guidelines or ask if none are apparent.
