I had one airline going to the rear right air spring which was scratched and leaking a bit at the compressor side. I went onto Google and found many posts, mostly on the RR.net forum, of people claiming you can easily cut the line back a tiny bit and then chamfer the edge with a pencil sharpener. So I did this. Big mistake.
I think the line is just long enough to still seal so the car is working, but I don't trust it now. So I am making this topic in the hope that people who have a similar issue find this and are warned.
On my P38 (1999 4.0 SE) the lines have a tiny bulge in them about 3cm from the end. This bulge doesn't fit in the push-fit connectors obviously. So cutting back is limited to a few mm, not enough to fix any damage/scratching. I cut back about 8mm and I think the line would go further into the connector were it not for the bulge.
Secondly, the lines are of quite a soft material. A pencil sharpener may not work. In my case the pencil shapener cut into the line and didn't nicely chamfer it, which meant I had to cut it back even more and try again.
Just a word of warning. I will have a look now at cutting the line back much further and installing a repair piece.
