Had the same problem on mine a few months ago, only even scarier!
Was popping over to my sister's late one evening, jumped in and turned the key; the engine tried to splutter into life but kept dying.
I tried to start it a couple more times and then was hit by an overwhelming smell of petrol!
I popped the bonnet to find the whole of the engine bay dripping with fuel with a large puddle sitting under the car.
The hose which is on the left hand side of the supply rail had blown off.
I think I was very lucky as the alternator was soaked!
I found that the hose, which was the clear type with webbing running through, had been crushed by the jubilee clip.
The following day, I disconnected the battery, unscrewed the fuel filler cap to release the pressure (boy, the 164 seems to run at very high fuel pressure!) and replaced the hoses on both sides of the rail with thicker black rubber reinforced fuel hose.. I've not had any problems since.
