from where to where does the vacuum hose that runs across the firewall go to? Its the one that's runs along the wire harness across the top of the fire wall. Any help would be appreciated. Its a 2.3 lima on a 91 ranger no a/c or p/s. I don't think this truck can came out any simpler. No Cruise Control, also theres a vacuum caracal. does the main center vacuum hose come off the lower intake or better yet is there a diagram that shows the vacuum setup formy model/ Thanks

 

if the label is not missing you should have a vacuum hose routing under the hood on the core support.

 

its missing. I can see where it probly use to go. 3 are put together and one for FPR and other is for EGR but don't don't know where the main goes to that carolsel and the one that goes across the fire wall?

 

Not sure how close it is to yours. Hope this helps.

 

The one that goes across the firewall may be the line that goes to the vacuum storage canister normally under the washer bottle.

Is the heater stuck blowing air out at the windshield?

 

Make sure that's not the water line from the windshield washer bottle to the squirters. Looks similar to a vacuum hose.

In my '97, the vacuum hoses (there are 2, one red and one green) to the vacuum canister is contained within a plastic conduit that also contains the vacuum lead for the EGR valve.
