vacuum pump

As already discussed here, an electrical vacuum pump is required to power the brake booster.

The pump is a used part, but in good condition.


The pump is controlled by a vacuum switch and the vacuum pump driver. This is also shown in the general wiring diagram.

mechanical setup

The mounting bracket consists of a base that is bolted to the battery box auxiliary frame, and a top part that holds the pump.

Mounted pump. It is essential to suspend the pump in very soft bearings. Otherwise, it will be terribly noisy. I have also put some butyl rubber dampening mats on pump and bracket to further silence it, and slightly throttled it's spin by a series resistor.
