Was wondering if anyone knows where these vacuum ports go, im trying to put the vacuum systym back together. Pic 1- a port behind the distributor going into the harness.
pic 2- back passenger side plenum rear port
pic 3- under the throttle body
pic 4- passenger side throttle body
pic 5- extra hoses that i have
ANY LEADS OR ANY INFO IS A HUGE HELP THANKS!!!
The 2 at the back of the plenum go to
1. From vac fitting on plenum To the checkvalve T near the distributor, that splits and one goes to the cruise control and one through the firewall to HVAC
2. from the vac connection at the plenum to a T near egr valve, one side goes to fuel press reg. The other forward to the air valves.
The small fitting on the underside of the throttle body comes out to the drivers side and goes to a T, one side feeds the EGR solenoid and the other goes to the left front to another T where the tank control and charcoal canister is. it connects to the tank pressure control and the charcoal cannister
.
The long metal tube goes from the pass side valve cover to the fitting on the throtlle body pass side. Caution passenger valve cover fitting IS NOT A PCV VALVE
the 1/4" plastic line on middle of the throtlle body is from the purge valve near the charcoal canister
the bottom on the throttle body is radiator coolant
