Question about installing catch can


Registered User
Ive read through all topics on catch can and think i understand ind how it works. so now ive decided to put on in because i keep getting an engine light. i can see that my suction jet pump has another small pipe going
into it.

It is connected to this pipe.

The question is does anybody know what i need to do with this? block it off? or can i install a catch can and keep that brake booster line in??

Thanks my car is currently in bits so appreciate any help
