Sir Ghosthunter,

i believe na-banggit na po sa thread din na to ung mga nakita nina bluegsr and raijuta na values.

vacuum reading would almost be the same after installation (2 inHg). before installation, depending on the condition of your auto. 17 inHg on the average, 20 kung very good condition pa.

Vacuum gauge is tapped at either PCV or brake servo.

Anything else sir?

Odee
