A customer requested us to install a booster pump to the aftermarket brake-servo setup on his 1967 VW Splitscreen bus.
Brake-Booster Vacuum Pump Installation.
It had initially been installed next to the brake servo, under the cab floor. But the noise from the pump had begun to frustrate the customer, so it was decided that a special enclosure would be created to house the pump, which could then be mounted in the engine bay to the left of the engine.
The pump dimensions were measured accurately, along with the internal space inside the engine bay, and a box was drawn up. This was fabricated and TIG welded out of aluminium.
The pump was mounted inside using rubber anti-vibration mounts, and grommets were used for all cable and hose exits.
Extra consideration was taken to allow airflow, by drilling holes into the bottom of the enclosure and standing-off the lid to allow the hot air to escape. Sound-deadening was also applied to the inside of the enclosure, and the enclosure was fitted to the engine bay again using anti-vibration mounts.
The vacuum hose was run to the front of the vehicle, and connected to the servo using a one-way valve to ensure the pressure remained in the servo.
