Forgot about this!
I got the stuff from Pirtek yesterday on the way home and fitted it last night. I used hydraulic hose and fittings commonly used offshore in the oil and gas industry so it should be up to the job. The hose is rated to 3k psi and I had the fittings crimped on so no worries there, and it cost £76 all in, apart from the fittings i needed from the rack, they were extra. In hindsight i could have got it a bit cheaper as one of the hoses is WAY too long but it does the job.
Still need to fire the car up and test it out for leaks, thats tonights job.
