So my vacuum pump gave up on Friday. First thing I noticed was AC only coming out of the defrost. I finally had a chance to look into it yesterday, and the pump is only pulling a couple inches at idle. Not even enough to work the HVAC controls with nothing else connected.
I’ve replaced more belt driven vacuum pumps on ford trucks than I can count. They have always seemed problematic. I can’t say that I’ve actually seen one last 100k miles. Others may have fine luck with them, but my point is only that I have no love for them. Also, I feel like I can always hear the darn things puffing away, and I don’t like it. My truck is already hydro boosted, so I only need vacuum for HVAC and cruise control. I’m also running V belts so no biggie to delete it.
I went ahead and ordered a Dorman 904-214 electric vacuum pump and pigtail from Amazon. It’s the pump for the superduty trucks. Does anyone know if that pump will pull enough vacuum to operate the cruise control? If not does anyone know what is needed to convert from the vacuum cruise control to the electric? The Haynes manual shows the same wiring diagram for both, but that doesn’t really seem likely.
The electric pump and pigtail were about half the price of a replacement belt driven pump. I should have it tomorrow. Plus it’s Amazon, if it doesn’t work I can send it back. I’ll be sure to post some pics of the install.
