ABOUT THIS TOOL

The Vacuum Gauge provides an easy and efficient

means of checking engine vacuum or testing fuel

pump operation.

NOTE: This gauge has been calibrated for use at

sea level. When using the gauge at alti-

tudes above sea level, you MUST correct

the gauge indication to its true value at sea

level by adding one in. Hg for each 1,000

feet above sea level.

For example: An indication of 19 in. Hg at 2,000

feet above sea level would be adjusted to 21 in. Hg

(true value at sea level).

CHECKING VACUUM

Checking Vacuum at Engine Idle

NOTE: Refer to your vehicle's service manual to

obtain the manufacturer's specifications

for vacuum.

1. MAKE SURE the ignition is off.

2. Locate a vacuum hose which is connected

directly to the intake manifold. Disconnect the

vacuum hose and connect the gauge in its place.

3. Start engine and idle.

4. Note the value of vacuum and compare this

value to the manufacturer's specifications.

If vacuum indication is LOWER than specified,

check for the following:

■ Incorrect ignition timing

■ Incorrect valve timing or adjustment

■ Incorrect idle mixture screw adjustment

■ Worn piston rings (cylinder compression)

■ Intake manifold vacuum leaks
