aaaaaaaalmost completed a swap from a 95 2wd s10 SS pickup to a 4x4 95 blazer.

things i found i needed to change:
distributor
oil pan/pump/pickup
coil
egr valve
very few other sensors... was a pretty direct bolt-in

i need a vacuum diagram, and have searched thorougly. i can provide pictures of things if that will help. on the passenger side rear of the intake manifold, theres a vacuum port. wheres it go?

driver side has 2 electric and vacuum controlled things... actuators or something... and i cant find where the rear port connects. does it connect to my gas tank vent line??

and finally, the tee fitting on the drivers side firewall. one hose connects to the ball thing on the hood. where does the other one go??

help would be great as soon as possible, ill be checking back frequently. thanks!

 

Nothing should be different from the motor you took out as far as the vacuum lines go.

The vacuum port on the back of the plenum should go to the 't' but should have a check valve in the line. From the 't', there should be another 't' with one line going into the firewall and another running down to your transfer case.

The stuff on the driver side rear is EVAP stuff. One line runs up to the throttle body (the feed side) while the other runs to the EVAP canister.
