Vacuum Pump Mounts
When mounting the vacuum pump I used the upper 2 mounts off a BMW that uses them to hold the oil filter housing to the body. The third lower mount came off a shock mount. It was in our junk shelf.
These pumps can be noisy so mounting them in rubber can help a lot. I still need to get a muffler device to install on pump’s inlet.
I installed an extra one way check valve in the vacuum line coming out of the pump going towards a tee. The other check valve is
I had to adjust the booster from running too long. The switch was pulling vacuum all the way to 25 inches.
I adjusted the switch to shut off the motor at 19.5 inches. When empty, it took 55 seconds to pull to 20 inches from 0 inches of vacuum. It took 30 seconds to repull 19.5 inches after applying the brake pedal. When applying the brakes, the switch will click after the third time ( around 13 to 16 inches).
The home made reservoir tank is 9.5″ long and 4″ wide, made with Black ABS material.
Reinstall left inner fender, power brakes are ready.
