The 13bre and rew engine has some thing called " vacuum chamber, and pressure chamber " where on the engine is this located ?

What are they connected to ?

Apriciate replyes on this, having trouble finding good diagram or manual on this subject.

If they are anything like the fd3s, they would be black plastic tanks loctaed in front of the intake manifold.

pressure chamber is the black plastic tank between the alternator and intake mani for the rew..

the vacuum chamber is the black plastic tank underneath to the right of the alternator...

Thanks...

apriciate it a lot.
