I have a fuel leak coming from the top of the engine ,it is a small length of rubber pipe where it connects, my question is it easy to replace and how are the clips
attached and does it need a special tool. Is the part number the one on the side of the pipe

the 036133725 and 8z0..... numbers that you can see on a couple of the components are the VAG part number - the 036 one is probably shared with other vehicles, the 8z0 is A2-specific

I'm having real trouble working out where this is - a photo from a bit further out putting it into context would be handy. Is this a petrol or diesel car?
The clip by your thumbnail can be sprung with locking pliers (small to medium size) and while held released, you can edge the clip further up the pipe until it isn't holding the pipe engaged with whatever is inside.

I used universal petrol pipe, it is very flexible.
As per Robin's message, the clips can be gripped with long nose pliers or the likes, quick easy job, and remove the smell of fuel from the cabin...as well as removing the potential for a fire!!!!!
MAKE SURE YOU DO IT WITH THE ENGINE COLD!
 
FSI fuel pipe, you can replace with good quality petrol hose from a motor factor/Hydraulic hose supplier(Hydrascand carry good quality hose)……….
Would certainly second only doing the replacement when the engine is cold, but would add not to drive or run the car with the leaking hose fitted the under bonnet temps are extremely high and this is also very close to the first cat converter.

Went to audi in Yeovil the cost of the part was £27.96 plus vat and no one in the country had one in stock
it would go on back order waiting 10 to 30 days, so went to local hose and radiator shop one meter of 8mm hose and new clips £8.40 now done and fully working

Thanks for advice

I always thought fuel line etc. hoses were somewhat specially made for the purpose material composition wise not to degrade due to exposure to quite nasty solvents (fuel) etc.

a standard hose might degrade fairly quick and be a ticking time bomb waiting to spray fuel all over your engine bay.

I'm sure the OP meant to advise that the local hose supplier had provided fuel-rated hose, but it was worth a post just to make sure the OP is aware there are different grade of hose for different fluids.

normally I would let this pass over my head , but if you think that I would have purchased one metre of standard hose for £8.40 then please think again, I would also have thought that the 8mm size would indicate that it was not normal hose
 
Just as a reminder to people and for general information the new fuels with added ethanol will degrade fuel hose.........its now worth keeping an eye on fuel hoses as part of regular maintainence, I recall a lot of concern in the classic car mags about possible problems with rubber fuel hoses.......one reason all new cars are fitted with nylon fuel pipes.

Fair enough, didn't mean any offense, better check than a bbq in the engine bay especially with ethanol content nowadays.
