Original Factory Part - NOT Aftermarket!
- MADE IN THE USA -
In the last year, the market has been flooded with a cheap imitation of this pump which is built in China. We have diassembled one of our OEM pumps and one of the aftermarket pumps side by side. The difference in build quality is substantial!
What does this part do?
This vacuum pump operates the heater controls and four wheel drive front vacuum hubs on your Ford Diesel truck.
It operates the cruise control on Dodge trucks with the Cummins Diesel. (Note: If your Dodge is equipped with a jake brake, there will be a belt-driven vacuum pump.)
What happens when it fails?
Fords: Your heater defaults to defrost only, and your four wheel drive may not engage if the pump does not run at all. Dodge: Intermittent or inoppeartive crusie control. The pump may also fail and run continuously - in this case, there may be a leak in the system which the vacuum pump can not keep up with, so it runs all the time. Disconnect the outlet hose and plug the connection on the pump with your finger. If the pump stops running there is a leak in the system - probably a broken line, etc. If the pump does not stop running when you perform this test, it is bad and needs replacement.
Does this pump fail often?
Yes, this is a very common failure item - Ford issued a TSB number 05-17-4 to advise their technicians of this issue.

Is it easy to change?
Yes! Anybody with a few simple tools can do it! As easy as changing oil! On Ford 7.3L Powerstrokes the pump is located on the passenger's side inner fender between the battery and the blower motor.. It is easy to get to. Just unbolt it, unplug the wiring, and carefully dismount the old pump from the rubber "feet" and mount the new pump. Plug the wiring back in, and re-connect the vacuum hose to complete the procedure.
Can this pump can be used for other applications?
Yes! - vacuum control systems, science projects, etc. - It turns on when current is applied and generates a vacuum of about 17 in hg. It then shuts off until the vacuum falls to 13 in hg when the cycle repeats. It will NOT work to power a brake booster due to inadequate volume.
Please note that ALL Ford pickups up to F-550, as well as all Dodge pickups use the pump pictured above with the round electrical connector. Trucks larger than F550 and Motorhomes employ a similar pump with a different connector (with two exposed male spade terminals). If you are using the pump for a special application, the pump with exposed spade connectors is much easier to attach custom wiring to. Please be sure to select the correct one when ordering.
