Looking for a basic vacuum line diagram as the ranger i just purchased has a mess off the 1 bbl carb. Manifold vacuum to hot air valve etc. I am sure that is not supposed to be there. Anyone know where to find diagrams or info of what goes where my haynes is not a lot of help.

 

There should be a temperature sensitive switch in the air cleaner that controls the hot air valve. The hose should not run directly from the manifold vacuum source to the valve.

Your best bet is a Ford Electrical and Vacuum Troubleshooting Manual or EVTM. It will have the electrical and vacuum diagrams for the entire truck.

 

Thanks Bart99GT, I will try to locate one of these manuals around town. I never knew they existed.

 

Hi Men: Just got an 87 Ranger for a backup/play vehicle. It's a 2.0 Liter Carbed 4 cyl. No mods. It is 2WD. New short block with less than 5k miles on it. I'm really dissappointed with mileaage. 13 to 14 mpg. Runs and idles good with no evident smoke. Could this low mileage be related to a vacuum problem as described in your thread? Thx for any guidance-jr

 

JR, check your underhood decal for vacuum line routing. If you have the factory carb, they used to be noted for sinking floats. The float was made of foam, covered w/plastic, and it would develop a leak, absorb some fuel, and not float so well. Then, they'd use a bunch more gas. I'd check the fuel level in the float bowl before assuming the float was bad. Your mileage should be in the mid to high 20's. You have 'close' to factory size wheels & tires, right?
After more thought, the carb I was referring to was the 2-bbl, but I bet you have the 1 barrel. I'd still check the float, as your mileage is low. You should make your own post about low mpg, and pull any codes from the ECM.

Again, try to find an Electrical and Vaccum Troubleshooting Manual, or EVTM for short, for your truck. It will have all of the diagrams you will need. You can try finding NEW ones from www.helminc.com or you can do a search on eBay as they do eventually go out of print. I picked up one for my 95 Ranger for less than $20.
