Its not that bad the fwd floor tanks on each side and centre floor tanks on each side are conected together by the standpipe interconect to maintain even fuel on each side and you have the interconnect valve on the rear floor tanks and crossfeed after the pumps so you can still get justabout all your fuel if a jetpump or boost pump fail !
If you want to see a sh1t fuel system just look at the Super Puma ,7 tanks, no direct crossfeed to the engines and only a mickey mouse "crossfeed" pump between tanks if it fails and the crew don't monitor the fuel levels between sides you have the potential of running fuel out on one engine and still having heaps to the other engine , this has disastrous potential if you are running a long range internal tank as it only feeds into one side!! not so in a Bell!
