Vacuum Supply

VACUUM SUPPLY
1. Disconnect the vacuum hose at the servo and install a vacuum gauge in the hose.
2. Start engine and observe the gauge at idle. The vacuum gauge should read at least ten inches of mercury. Shut off engine, the vacuum should continue to hold 10 inches of mercury.
3. If vacuum does not meet this requirement, check and correct the following vacuum leaks:
- Vacuum lines
- Vacuum reservoir
- Servo vacuum
- Poor engine performance
