The vacuum pump is located at the rear of the engine, adjacent to the HP fuel pump. The pump is attached to a machined hole in the cylinder head, sealed with a gasket and secured with three bolts.
The vacuum pump is driven by the inlet camshaft. Two tangs on the pump drive shaft mate with two slots in the end of the inlet camshaft and provide a positive drive between the two components. The vacuum produced by the pump is used to provide a vacuum for the brake booster on the braking system.
