TPI Vacuum Lines
Hi, all. I am preparing for a TBI to TPI conversion and am in need of the vacuum hose diagram for a 90-92 TPI. Since I have a state emissions test comming up soon, I would like to have all the vacuum related devices and sensors working. I have compared the TPI to the TBI and found most of the obvious things like PCV but the TPI has 2 or 3 more connections to fill. I have the Chevy service/shop manual and have looked at every page but no vacuum lines drawing! Help?
