Re: 86 iroc vacuum diagram for 305tpi

Jeff, Let me know if you have one good diagram for all the vacuum lines. I am going through the same thing on my 1986. I swapped from Carb to TPI and have it running smoothly but realize some of my vacuum lines cannot be right. The evap canister is not hooked in properly I can tell that. What part number is on your Evap canister. I took over the parts from a friend for the swap a while ago and want to make sure I have the right canister. Thanks and I hope we can share knowledge. I found a few pics of things but nothing really simple, I would be glad to send you what I have found so far. I Pmd you my email and I will send you the power point I put them into. Thanks Tony
