Installation step
It is designed to supply your brake booster with a steady vacuum between 18”-25” Hg. Pls confirm your request before buying it.
Step 1.First,install the pump in a suitable location using the rubber insulators to mount to the vehicle.We strongly recommend the unit is mounted to a frame rail or other solid mounting location.
Step 2.Next,wire the fuse red wire to a positive(+) ignition switched 12V power source.Black Wire to Ground.
Positive(+) connection must be a switched source , or pump will run with key off
The circuit used for connection must have an 20 amp fuse
Step 3.Then,connect the vacuum pump connector to the fuse wire harness connector.
Connect pressure switch connectors to the other two wire harness connectors.
Step 4.Lastly,connect the vacuum pump inlet port to Power Brake Booster by tube assembly. Clamp each connector fully.

Worked great out of the box. Tested it and found this fixed the issue I was having with my low vacuum at idle 327/365 Corvette engine. The power booster wasn’t working properly. Vacuum needs to be above 18” of mercury at idle. This improved my stopping power by 50% and reduced my stopping distance by 1/3rd. Excellent stainless steel bracket and hardware. Mine came with no instructions as the box was opened, but it’s east to put together and mount. No issues so far.

UPDATE: The new part works great. It was inconvenient to return and order a new part, but this second part works perfectly. Might just have been 1 out of 100 that just wasn’t right. We all know this happens sometimes.I ordered the pump and installed it correctly. I check the vacuum for leaks and there were no leaks anywhere in the system. The pump will not shut off. It will turn off for a second and turn right back on. There is something wrong with the switch. I tried to exchange the item and had no luck. So i had to settle with returning the item. Now i have to wait for the return to order a replacement.

Got this to replace the mechanical vaccumm pump on my diesel truck. The mechanical ones are only lasting about 40,000 miles. This pump was super easy to install and works great. I did use a 1/16 inch thick piece of rubber betweent he pump and the fender I mounted it on. Very quiet. Like an electric fuel pump. I can barely hear it with the engine off. It draws down quick to 24 on my gauge. I will update with milage when I have to replace it. Sooo much easier tha replacing the mechanical pump.

Hooked this up too my street rod which has a big cam and was robbing vacuum from the brakes. Installed this and brakes are much better

The system was easy enough to install, even though the information pages were barely legible: When the ink is low in the printer, replace the cartridge.The kit was complete, no surprises.The pump is reasonably quiet and worked properly for a short while: cycle on then off a number of times while cycling the brake pedal; as I expected it should.The next day I proceeded to do some more refining of the installation when I again decided to cycle the vacuum system. However, the pump would not shut off on low vacuum, but would run for six to seven seconds, pause for 1/2 of a second and again run for six to seven seconds. It ran for three minutes before I decided to unplug the pump as it was getting very warm. After several minutes I proceeded to pull the check valve from the brake booster and noted a loud and distinct vacuum sound from the booster reservoir, so the pump was producing a deep vacuum. The relay was cycling, so the only item that appears to be not working is the four wire vacuum control switch.There is no service parts availability or contact information associated with this supplier.My advice is to avoid this company until they provide service parts for previous and potential future customers.I could have given them four stars if I had access to those parts. Even the best of companies have those occasional part failure, but don’t leave me high and dry with no access to one little part of this vacuum braking system !
