Hello. My 1995 UK RHD RS2 fuel line(s) (certainly the high pressure fuel line) are leaking fuel about half-way along the length of the car where there is a securing bracket. Leaking when parked up and switched off. Leaking more when the fuel pump is engaged and the engine is running. Probably caused by corrosion from 29 years of driving with salt on the roads. The fuel lines in the engine bay look fine. The fuel lines at the rear of the car look fine. The fuel line is straight (not bent) where it is leaking. I daren't undo the securing bracket to see if the non-high pressure lines are leaking too in case they all fall apart.
The car still starts and runs (but the fuel is disappearing faster than usual). I live near Twickenham (paying £12.50 per day ULEZ for the pleasure of driving).
I have a few questions:
1. Which is the best option for replacing the straight part of the high pressure fuel line in terms of material (steel to keep the RS2 as original as possible or some newer material?; what should be used for the high pressure connections?)?
2. What are the inner and outer dimensions of the fuel lines?
3. Where are the best places to cut the fuel line(s) in order to connect the replacement section? I saw a connection near the back of the car for the high pressure fuel line but I did not see a connection for that same high pressure fuel line towards the front of the car (other than in the engine bay).
4. Where can I purchase the parts that I will need? Either off the shelf or manufactured for me?
5. Who is best placed to do the work? The mechanic who looks after my car has told me he can do the work if I supply all of the parts, but should I be taking my RS2 to a fuel line specialist for this instead? If so, to whom? I am not a mechanic and am incapable of doing the work myself.
6. The fuel line closest to the side of the car is the high pressure fuel line but what are the other two fuel lines? Are they both return fuel lines to the fuel tank or is one a breather line? Which is which?
7. Does the RS2 have fuel lines that are unique to the RS2 or are the RS2 fuel lines on other Audis too? Is so, which other Audis?
There are no doubt helpful posts on this topic elsewhere in this great forum but I did not find exactly what I was looking for when searching. I am sorry if I have missed an obvious post on this topic.
The MOT is due on 23 March so I don't have much time to sort this.
Any help will be gratefully received.
Many thanks,
Jon
