Thinking of re routing my brake booster hose from running along behind the engine to run from the manni, along the fuel rail and to the servo that way. Theres 2 non return valves on the line. Could i replace them with a single upgraded metal one? I will be using stainless braided hose

Yes you can :-)

Cheers clive, does it matter where i position the single one way valve?

Position makes no difference as long as they are fitted the right way round. I would call metal ones upgraded though, they are different but not an upgrade lol

Looking to get this one

Would it do the trick?

I'm planning on doing the same - eventually!!

Sounds like you got lots to sort already mate, you will get round to it lol
