Had a phone call from TPS today - after 2 weeks of being on back order, the hose turns out to be NLA
Not sure what I'm going to do with it now tbh. Hose suppliers look at me like I've got two heads when I ask for brake-fluid resistant hose. Apart from HEL of course, but theirs isn't big enough. The factory rubber hose has such tight bends that OE clutch hose won't bend that tight, nor could I bend metal pipe that tight either.
Possibly I could cut the bends off the hose and use alloy tube for the main run across the bulkhead. Or maybe just encase the original hose in adhesive-lined heatshrink...
Oh, and after tinkering and measuring and pondering, there is no space for any other model's fluid reservoir

The recess in the bonnet is so tight around the reservoir and the m/c is so high in the car there's no option other than the proper one. I'm going to try various ways of cleaning my original reservoir in the hope it won't sweat with new fluid, and if that fails I'll import a new one from ECS. Its £150 to buy in the US with the crap exchange rate, but even with postage that's cheaper than here. I have plenty of friends in the US who can post it for me.
