I owe it a lot, especially after hundreds of hours spannering, and hundred more sanding, filling and painting. Happy days.
Thanks Nige for the PTFE outer idea, I’ve been on eBay and securing lengths >2m seems to be the issue, though I have found a 5m run from China (prob infers a ‘no’ that). Q - is this material hard, ie will it resist the odd light knock and NOT deform around light radiuses? I saw a hardness factor of 55, but tbh have no inkling of what that means practically.

Just think Lobo could have had a BMW Imp now 🤣🤣

Ptfe tube, I was looking at this supply (although uk) https://www.amazon.co.uk/BZ-3D-Transparent-Filament-Extruder/dp/B07YBX7GJN/ref=sr_1_3_sspa?keywords=ptfe+tube&qid=1673301148&sr=8-3-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1tgat had 3mtr as listed that may reach.
You can more easily get PU or nylon in larger bore to sheath the ptfe and give measure of protection from outer abrasion, kinking etc and provide an overall solution.
These type of materials are frequently used in pneumatics etc and so may be supply route. We used them in factory environments for air driven machinery, virtually all barrell (metal screwed pipe) disappeared from those systems apart from main distribution from compressors. The small bore has to be run with some radius to avoid kinking but generally the material is highly resistant to most vibration etc. The two together with ptfe internal should give good support from as it increases wall thickness significantly.
We also ran both rigid and flexible chemical system and I used double tubing like this to get under an outside building to building connection that required bunding for groundwater protection risk. I could run a couple of "umbilical" lines through a clear outer to offer containment with visual inspection from leaking primary to arrange attention if required.
More to show the thinking process around using things like this for solution.

Trivia, once working for a company completing warranty work at houses, knocked on a door and William Woolard opened it :)
Also the Sweeny, John Thaw at another. Not on the same day you'll understand, that would be freaky ;D

Not name dropping - when I worked at Mercedes-Benz of Derby we had a used LWB S600 (V12) in the showroom - it was sold by an American Salesman over the phone to a customer in a hamlet near Surrey.
As two Lexus Saloons (both very old ones) were traded in part exchange I drove to Surrey with the salesman to deliver the Merc so we could bring back the two Lexus Saloons, The address was a cottage name down a country lane in the middle of nowhere. No phone signal fo ring the customer so after a while we pulled up outside this isolated pub in the afternoon.
I went into the pub & asked the Landlord if he knew the address we were looking for - he said he had never heard of it. We had to drive back up the lane for almost 2 miles to get a phone signal - we rang the customers landline number telling him we could not find his address - he said its at the back of the pub on the other side of the 20 ft Leylandai trees.
We drove back to the pub & spotted a well hidden gravel path to one side - as we drove onto the Cottage frontage out came Bob Mortimer to greet us!
Bob Morimer told us the Landlord was just trying to protect his privacy. He was nothing like his TV persona at the time (Shooting Stars) he was more like the Gone Fishing version - he was a pleasant normal person with no vissible sense of humour.

Thanks Nige for the further infos. In the last few hours I’ve found a 7mm OD Bowden sheath, nylon lined (25’) which I’ve ordered at a doable £25. It’ll provide the protection I want give the exposed run below the cabin / through the x-beams.

On your way to a solution then at least. Generally examples with handbrake cables fully covered for entire length I find don't give a problem over many years. You'd expect something similar in dirt exclusion and free movement in this as a sensible mod too.
