    • A great alternative for 2011-2012 F150
Review Image by Mike Mike
The media could not be loaded. I had replaced my vacuum pump in my 2011 F150 about 3 years ago and it cost about $350 , here we are it was making noise again and now it’s close to $600 for the same part. I just can’t spend that for something that should be $200 max. This can be made to fit with a little threaded rod and nuts/washers. I also used the solder shrink tube and used the connector from the old pump. I now have a pretty much silent booster pump and it works great. Time will tell how long it lasts but at 1/5 of the cost of a ford unit I’ll take that gamble but so far so good and this unit pumps down as fast if not faster than the old pump. ... show more

    • Great pump, low price for vacuum brakes.
I bought this vacuum pump to add to the braking system of a 1977 corvette that had a high horsepower 383 installed. The motor produces very little vacuum for the vacuum assisted brakes. This pump, along with a vacuum can and several vacuum check valves, restored my braking power. You NEED to use a vacuum switch with this product, otherwise it will continue to run continuously and burn up. When I turn on the ignition, I can hear the pump run for about 5 seconds, then it shuts off. This lets me know I have about 17 inches of vacuum available for the brakes. Once the engine is running, I can't hear it anymore. I also plumbed in vacuum from the engine (at best 11 inches) so the pump gets supplemented with engine vacuum when it is available. This pump, a vacuum switch, and a relay cost around $150 total, which is less than a complete system from Summit or Jegs. Works good. I hope the pump lasts a long time. There is a logo on the pump that says "Hella" so I'm sure this is the same pump used on a lot of European cars that require a vacuum pump. The trickiest part of this pump is finding a good way to mount it.....you definitely want to use the rubber bushings to mount it to reduce noise and vibration. ... show more

    • Perfect for a hotrod with low manifold vacuum.
The pump is quiet, rubber damper mounts, simple to install. Can't go wrong here! OEM quality.

    • Works great!
I bought this for my 72 GMC K1500, my engine has a large cam and doesn't produce much vacuum for the power brakes. I purchased this with the suggested vacuum switch and it works excellent! Better brakes than ever! It produces a lot of vacuum very fast, it's very quiet and smooth running. I connected it directly to my battery to get the most amperage I could then bought a relay connected to a key switched circuit in the cab so it only runs when I'm driving. I would definitely recommend this pump and switch for anyone needing vacuum for brakes. I use the vacuum pump alone meaning I no longer have the manifold vacuum connected to the brake booster. I would recommend getting a vacuum canister as well, found one on Amazon for around $20. I'm very satisfied! ... show more

    • Perfect swap for hard brake pedal on start-up.
Bought as a replacement for a brake problem on my 08 Cadillac CTS with the 3.6L DI. Took 5-10 minutes to swap. Works great. My old one lasted 7 years. Hopefully this one lasts at least that long since I don't plan on owning my car that long. Supposed to be the same pump for all cars with this motor, which is a lot of cars, but check first. I know it works on the CTS. ... show more

This pump will pull about 25hg of vacuum on a Mr. Gasket 3701 vacuum tank in around 10 seconds. It does not have any sort of regulator to shut itself off, you need to use another controller or it will run and run and run and probably eventually burn up.

I installed this on a supercharged muscle car. I don't have much time on it yet but it seems to work fine. Keep in mind that this pump has no non-return valve in it. You will need to add a check valve to make it work properly.
