3) if fuel leak could cause fire, (IE SPRAYING near nacelle) SHUT IT DOWN!!!! you should have plenty of gas to get back with one full wing and centre tank. Might be wrong tho. Do some perf sums at worse case (PNR?) and see what figures you get.

Not really sure where the selector valves and associated plumbing are located, but I doubt that a non-selected tank could leak into a zone where an operating engine could ignite it. Even if the leak were in the wing lower surface directly over an engine, the worst that would happen is the fuel would be blown away by the cold fan exhaust.
