I heard this authoritatively from the engineer who signed off the design of your aeroplane FFF !
Well, I won't argue with him! He did also include a reserve tank in the design, to give me an hour or so of extra fuel if the worst happens, which is a very handy safety blanket - even though the guage been totally reliable in my experience so far, I don't particularly like not being able to see the fuel level visually.
