Vacuum pump (firewall passenger side)

Hi all,
The vacuum pump continues to run . disconnected hose no vacuum. Where do I purrchase? how do I spec this out ? description?

04.5

 

I did find some cheapys on ebay generic for 39.00 .

 

It is a generic pump, Chevy and Ford used it to.
You can find it everywhere in parts stores and online.
I don't see big differences there.

Only use for that pump is the cruise servo.

 

Thanks Ozy. Just getting my 04.5 ready for sale.

 

Ozy so it wasn't the pump . I chased the hose and it T's off into the firewall. Guess I need a schematic

 

Behind the wall is just a little vacuum tank, nothing more, this line is a cul de sac.
If needed you can access it through the plastic that sits above, wipers need to be taken of for that.

 

Thanks

 

What trucks use a vacuum cruise servo? I think mine is all computerized.

I don't know about the Manuals.
