I finally got the OEM instrument cluster element with vacuum gauge for my car. I hope it'll fit. What I want to ask about is - would You suggest any modifications to it before I put it in the car?
It looks pretty straightforward to me - when the vacuum increases the needle points to the clear zone, and when it decreases it goes to the red zone.
I can't wait to install it, but that will be possible next week only if everything else will turn out OK.
