Fuel Line Problems

[320pilot]

2006 320CDI coupe

Returning home yesterday I put my foot down to overtake a tractor and half way past it the engine misfired badly so I immediateley pulled over on to the grass verge. The engine was still ticking over as normal so I set of again. As soon as the revs reached 2000 ish it started to misfire badly. Luckily I could still manage 50/60mph doing this so arrived home ok. It was then that I could smell diesel fuel and on further investigation this morning it seems one of the braided hoses is leaking badly. I can't get underneath to see which one so can only view from the top with the nearside air filter removed.
Obviously they will need replacing. Has anyone attempted this job? Advice on part numbers, availablity etc would be great help.

Sounds like the leakoff pipe, air is getting in and causing the misfire. Any pictures of the leaks?

Thanks Alexander. Unfortunately I can't gain access to the pipes. Are you suggesting that the leakoff pipe has just come adrift or may be broken?
