As mentioned (for the Nth time) the fuel system couldn't be simpler.
From memory, there was a tendency for some pilots to switch the boosters off to prevent the captions from illuminating after a while sitting nose up. Departing the hover removed this issue but you had to remember to switch the boosters on again during cruise!
Three fuel tanks, two priming pumps, two transfer pumps and pilot must intervene in order to not run low / out of usable fuel? Oh and don't confuse which switches to switch them on and off according to attitude when low on fuel. That's simple?
They are transfer pumps, not boosters...
