  1. My model of MX-5 is: __ nc1
  2. I’m based near: __ Blyth
  3. I’m looking for technical help or recommendations on: _

Anyone know if a silicon hose is available for the large hose that is found on the top of the power steering fluid reservoir ?

I would think it’s unlikely as I don’t believe that silicone is very resistant to oils/atf.

Yeah I thought maybe as it’s above the fluid max level it may be a vacuum hose ?

I haven’t figured out the pipework for an NC, but I though it was the return pipe to the reservoir - hopefully somebody more knowledgable could confirm either way.
