Gems vacuum circuit
Posted: Wed Aug 21, 2019 6:17 am
Good morning folks,
I've some doubt connecting vacuum system in my Tomcat.
As shown in pics, i found 4 vacuum takeoffs, 2 in trumpet base and 2 in plenum.
Take off nr. 1, left hand side of the plenum: unknown, maybe is part of idle circuit?
Take off nr. 2, left hand side of the plenum: connection of the PCV system, left hand bank
Take off nr. 3, left hand side of the trumpet base: connection to fuel pressure regulator
Take off nr. 4, right hand side of the trumpet base: probably is the other connection to the PCV system, right hand bank where oil separator is fitted.
I can't find:
- the purge hose connection (if present)
- the connection for vacuum brake booster
