Fuel leaks

for the last few days the fastback has had a fuel smell and seem to be useing lots of fuel.No obvious puddles underneath so thought maybe the chokes were sticking.The right carby was wet so i cut the safety wire to tighten the fuel line clamp & the whole lot fell off, the only thing holding it in place was the safety wire.

The golden rule , replace old fuel hose and use clamps and safety wire.

Where should the 'safety wire' be? I dont think I have them, at least there is nothing made of wire in the vicinity
