i am finishing up a TPI conversion using a 92 TPI unit. I have a couple easy questions for the TPI guys. I did look at the TPI vacuum diagram but it sucks.

1. there is an umplugged vacuum line on the drivers side front of the intake. it runs under the upper plenum and i think it connects to the EGR. where do i plug up the end at the front of the intake?

2. on the passenger side rear there is a large vacuum port. what is it for?

thanks

1) does it have a 90 boot on it? should connect to port on bottom of throttle body.

2) i have a similar port on mine, but on the driver side (91) but mine goes to the PCV on the valve cover.

 

1. I have a K&N filter on the end of the Throttle body so no 90* boot. did it originally connect tot he boot or the TB?

2. I have the PVC and booster connected on the drivers side. I can plug the one on the passenger side but i wanted to know what it went to.


thanks

I dont know what you would consider large. But on the passenger its probobly going to your EGR solenoid, or maybe your MAP.

 

Large port on pass side of TB is for a filtered fresh air source for the PCV - that port connects to a nipple on the pass valve cover. PCV has to have an incoming air source to be able to suck anything out the drivers VC.

Did you do a search? I justexplained all this a week or two ago....

 

thanks for the help. I have done a search. I got the one ont he front connected. it is on the drivers side rear bottom of the TB. I will take a pic of the other one.
thanks

BTW. I did a search but the vacuum diagram that comes up looks like a 3rd grader drew it

 

Sorry for the tardy response - been out of town and no access.

The vacuum port on the TV bottom driver's side os for the EGR solenoid.
