Vacuum hose routing with MP plenum

Condor232

Registered User
I have a MP inlet plenum and no EGR system. I am struggling with the vacuum routing. Please keep in mind this is a Mustang.

Anyone have any advice for this kind of setup, where to run the lines, etc...

Currently, I have the following and what to know if I have the right idea:

#1 - capped off
#2 - brake booster
#3 - connected to TB plenum
#4 - Fuel Pressure Regulator
#5 - Connected to Inlet Plenum (#3)
#6 - PCV?
#7 - cap off?
#8 - connected to boost valve

#1 is for the boost gauge.

#7 would be the PCV

#6 not sure.

It seems like the others should be ok if not someone else should chime in and let you know.
 
1. Boost gauge
2. Block it off
3. Crosstalk to 5
4. Fuel pressure regulator
5. Crosstalk to 3
6. PCV
7. Brake booster
8. Bypass valve

Nowhere in the Ford service manual is there a mention of a “crosstalk tube”. The small brass "T" fitting on the lower plenum is called an “aspirator”. The aspirator has is a small venturi that provides a small amount of vacuum to the cruise control servo under boost conditions.
