1. Turbo Boost Vacuum Reservoir (then to Turbo Boost Pressure Converter)
2. EGR Pressure Converter
3. Engine Mount Pressure Converter

Pretty sure I don't have any vacuum line feeding anything on the intake manifold (swirl flap control etc.?)
So strange , they told me they have different vacumm level. Maybe becouse the first pipe was broken and it had glue on it , the glue might have gotten inside and block the line or maybe it was leaking vacum.
Mine has a line that feeds the intake manifold to open swirl flap
This is the old picture with the old vacum line : https://imgur.com/Y5pi2hq
