I have just reinstalled a rebuilt 3.9L V6 for my 1994 Dakota. I two vacuum lines that I cannot find a home for! One is very small and comes out of the fire wall just below the heater hoses. The other T's off the line that comes out of the middle of the intake manifold on the right side. One half goes back to the fire wall and I have that connected. The other half, is a smaller hose, goes towards the front of the manifold. Any help will be greatly appreciated.

 

The small vac line comeing out of the fire wall leads to the evap canister on the passenger side fire wall, the line coming out of the intake that tees off one side goes to to the evap purge soleniod and the other side goes around the back of the engine to the transducer for the EGR valve. If you need a scematic let me know and I can e-mail it to you.

 

There should be a diagram on the underside of your hood.
