Went to change the vacuum pipe (rubber one) between VNT solenoid and metal pipe from vacuum reservoir this afternoon. Was surprised to see that the fittings on respective components are different sizes. Needless to say that the vacuum hose supplied to me from a local motor factor did not fit at both ends.... would fit the solenoid alright. I immersed one end of new pipe in freshly boiled water in the hope that it would expand enough to fit on the metal pipe...alas it did not.
Question is; Are the rubber vacuum pipes formed hoses therefore only available from a dealer?
I will try other avenues because Alfa dealers in this part of Ireland are generally 'confused'
