A great alternative for 2011-2012 F150
Review Image by Mike
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

This is a good replacement for my old vacuum pump. I used this part on my 5th gen camaro lt. On the camaro this is used as a brake booster and to add vacuum to the intake. My vehicle would crank with no start. I swapped out my old pump for the new one and started up with no issues. The installation was quick and easy. The pump has been working for 1 year with no problems ... show more

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.

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

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 for EVs
Excellent vacuum pump for Electric Car conversion. I am using this one for a Chevrolet Swift (Geo Metro Sedan) electric car with a vacuum switch, a vacuum tank and a relay. The system works very well, with very low noise and no vibration. The pump draws about 7 amp max at 12V

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.
