Not wanting to upset the apple cart...but stainless steel overbraid PTFE lined brake lines are unacceptable on a road car officially...never heard it about braided fuel lines and ive SVA'd a few cars with braided fuel lines but they have run internally rather than externally but the brake lines in PTFE stainless overbraid are defo (illegal). With regard to the argument over use of briaded lines....Subuaru WRC cars are now mainly plumbed in solid lines...brakes & fuel....but it is a weight reduction and perfomance factor...nothing to do with SVA or MOT...

IMO Braided hoses still look the best.....
