This was my attempt to go to AN with teflon line from a few years back.
I quickly ripped it out and sourced another rubber high pressure line due to the surging/pulsing feedback, especially at full lock.
There probably a reason why the OEM high pressure line is so long (does a loop on subframe)
Rack side, i used hardline fitting.
Flare where it connects to hardline from pump (near brake cyl) was a M14 x 1.5 inverted flare from memory
