1980 Ford Ranger F-150 4x4 351 engine. Reverse went out of the transmission so I replaced the transmission and sometime while working on it 3 vacuum lines came loose from the tree that connected to the firewall. Now I don't know which hoses go where. I have one hose from my air cleaner, one from my modulator on the transmission and I can't find the other one. The other one would be the one that makes the rest vacuum. so that the mopdulator will let the tranny shift. I just can't seem to find it. ANy one know where it comes from or maybe where I could find a vacuum line diagram or something??? Anything helps, I have looked everywhere. Thanks
If your vacuum supply line is missing, it will have to come from the engine. The engine is the source for the vacuum. Usually behind the carb there is a tree were several vacuum lines are hooked in.
