Thanks Lynn, that's what I was tending towards. If I didgdo to Dot 5 I probably would have run new lines anyway so everything would be new, but the existing lines are great and would be a pain to re-run. The old fluid gave me 12 years and who knows how many more had I not gone all nervous (plus covid spare time). My only problem was fluid boiling in the accelerator slave which is located right below the manifold exhaust pipe. I have since installed a heat baffle that seems to have solved the problem.
