Hi,
I searched the forum and did find some info on vacuum line routing for a 90 cherokee 4.0, issue is I found 3 lines that had holes in them that seemed to go to the canister. When I pulled on them though more than 3 came up as they were taped together. Now one of them goes to a port on the exhaust manifold, I fixed that one. The other two were going to the heater and the cruise control. What I don't know is which line goes to the canister, the cruise or the heat. Now there were a couple more lines, one had a coupler.. What did it couple to??
I inherited this jeep, and the reason I want hunting for leaks is two fold..it was running very rich and it did not pass smog. I simply can not find a diagram that specifically shows lines connecting in this area.. Any help would be great...thanks in advance.
