Yes, and the lower pipe was successfully planted into the union using the same long screwdriver trick. Does need to be an extra long one though - 12” is not enough. The job is now done and power steering restored. Here is a synopsis of how this job went.
1. Access is difficult, but it is possible to remove the old line intact and install the new one without removing anything apart from the offside wheel to access the lower union. 18mm flared nut socket wench and 18mm crows foot with extension bar are needed together with decent set of sockets and tools.
2. If possible replace the old line with a new one. At this time, OEM Puma 1.7 lines are still available on Ebay for £226 + £30 for the two unions. Replacement means you can cut off the old pipe above the union and use standard 18mm socket and extension to remove. This will save a LOT of time.
3. Otherwise you can try to get the old pipe repaired or better still buy a good secondhand one (rare + expensive). The only S/H one I could find was £180! - makes the new one seem a bargain. I contacted 2 power steering specialists about repairing. One would not touch it, the other would fix it, but leave out the pressure switch, which for me is not a good solution.
4. Fitting the new pipe is quite easy. First, install the unions using 18mm socket and tighten. Some PTFE on the threads is recommended. Next, route the line correctly and the pipe ends will be next to the unions. Do not bolt the brackets at this point. Coat the ends with some PS fluid and push in. It should click in and will then stay put permanently. Note my earlier comments on this.
5. Now fill up the PS reservoir and start the engine. Move the wheel from lock to lock a few times. PS should be restored, but there maybe some noise from the pump as more PS fluid is needed.
6. Switch off engine and fill reservoir again. Restart engine, should be all good now.
7. Check for any leaks and if all good, bolt the line brackets to the fixing points, connect the pressure switch and now you’re good to go.
