Tool Usage Instructions
A. Fuel Pressure Gauge (TG-31119-001):
Refer to the fuel pressure gauge instruction booklet included in the ITK-4 Test Kit.
B. Differential Pressure Test Gauges (TG-005 & TG-010):
•
Both the TG-005 (0-5 PSI) and the TG-010 (0-10” WC) are differential pressure gauges. This
means they can be used to measure the difference in pressures between two separate areas
or they can be used to measure either positive pressure or negative pressure (vacuum).

TG-010
•
Before using either of the differential pressure test gauges, they should to be calibrated against
a manometer or
known
calibrated gauge.
To calibrate a gauge:
Remove the front cover by unscrewing it in a counter-clockwise direction. You may need to
use a pair of channel lock style pliers (be careful as the cover is made of plastic). DO NOT use
any clamping tool on the body of the gauge.
