If anyone has a part number for the vacuum actuated valve that I need, I'd appreciate it. Partsguyed doesn't seem to have a phone number and hasn't returned my email yet (probably hasn't seen it because of other business) but I need to get this replaced very soon.

When I search other sites, like RockAuto.com, I find listings for "Heater Control Valve" but the image isn't even close to what I see in the truck.

I wouldn't be so impatient if we didn't have another trip planned Thursday through Sunday, that involved sleeping in the Ex at the track. Heat would be nice, not worrying that the part is already leaking and might fail catastrophically would be great...

If I can't get the part in time, I'm planning to remove it and install a connector to eliminate it, then cap the vacuum line, until I can get the part.

 

Check horizonford in Seattle and call them. Ask for Ed.
