ERA Turbo Forum

I just sent them an email, waiting for a reply. Everyone ive talked to so far has told me its discontinued, which isnt a surprise and the one shop that shows inventory on the part hasnt gotten back to me yet.

I am currently looking for a 'Piston-dump valve', anyone know where I can order one? Its part number in the microfiche is 'TAM 1137', since its not an ERA part it was probably used on the Metro as well?
