Hi do power steering lines need to have crimped fittings or can I use A N fittings as used in fuel lines that use braided line I'm relocating my pump to the boot

Sorry for the delayed reply, I had to consult an industry expert on this one, and I've edited down his reply below:
The end fittings are not an issue, and will do the job.
However, with the lines you use, there are a number of things to consider.
Most braided lines are not going to be up to the job, despite their catalog claims. So taking the long term view, the suggestion would be to use steel lines, and if you are looking at running the line through the cabin, use bulkhead fittings, with a short flexible hose (refer below about hose type) at each end of the bulkhead (outside of the cabin).
If you did specifically want to use braided, use a teflon/nylon style hose, but be very aware that they transmit a lot of noise/shock, and are very prone to failure if exposed to heat (such as passing near an oil filter, or even a solenoid). Also you are likely to have to increase the line size used, particularly for the return line.
A couple of people to talk to, would be Phil from PG Hydraulics (who can get rubber power steer line made up to suit, and for general guidance), or to Steve from GSS (Greenlane Speed Shop) regarding what type of braided line to use if you did decide to stay with braided.

Carrying this thread on a bit but I also intend to run a electric power steering pump and was wondering if I can run by the existing fuel brake lines using the old HICAS in a (R32 Skyline) lines (steel) that went to the rear this would simplify things and be running out side the cabin I know this requires a Cert is it mainly looking at the the Lines are correctly installed and pump is secured safely...
on a side note if you removed the HICAS by completely swapping the rear subframe to a non HICAS factory vehicle does this need a cert?

While I am not specifically familiar with the HICAS lines, they should be suitable, as they are steel hydraulic lines previously used for power steering fluid.
Yes, removal of HICAS by changing a subframe will require certification.
