Upgrade vacuum pump?

I've gone through several vacuum pumps through the years on these OBS 7.3's and was just wondering was there any upgraded versions available?

Could I go electric? Or would my cruise not work right? Just throwing some ideas out, I searched and looks like one guy was gonna try it but I never found where he actually did it. I can tell mine is getting weak again, and if all else fails, I will go and get a motorcraft pump straight from Ford this time. Maybe I'll have better luck out of it.

The cruise is electric as is your throttle. What the vacuum pump is used for is the brakes and HVAC. If you want to swap to a electric pump from a SD, you need to convert the brakes to a hydroboost system.

I was just wanting to get away from the mechanical vacuum pump that seems to have a very short life. The cruise may work off of throttle position, but my cruise will not work when the vacuum pump goes out. It's happened to me too many times in 2 different 1997 powerstrokes. I didn't know if a constant vacuum would mess with the cruise or not. I may try to find one and just mock it up to see how it works. If all else fails I'll just buy 2 mechanical pumps next time and keep one in the tool box. Ha!

It's most likely the brake system shutting down the cruise when it senses that you have no vacuum. The F-Superduty used a hydroboost system for the brakes that uses the power steering pump rather than vacuum. You could swap to that and use a small electric pump for the HVAC.

Oh ok, yeah I was aware of the newer versions not using vacuum on anything and using the power steering pump pressure for the brakes. Not sure if I want to do that much customizing, the brakes and all work just fine off of vacuum, it's just the little cheesy pumps that keep going out. I'll look into an electric pump. Thanks.

I don't think you will find a suitable electric vacuum pump that has the capacity needed for our brakes. Cheers!
