Others may disagree but in my opinion if it just cuts out and back fires when trying to start it's spark not fuel related. The back fire is the fuel igniting so fuel must be there, also fuel related I would expect the bike to lose power and baulk with throttle but possibly tick over (badly perhaps) you in theory have four fuel systems except for the pump I supose, but what are the chances of all four failing simultaneously? Anyway I'd be looking at ignition not fuel, good luck.
