Preliminary Steps
1. Read instructions thoroughly. Please consult a qualified mechanic if you
have not had training in the proper installation of instruments.
2. Determine ideal mounting location. Consult your vehicle's repair manual
to locate:
A) Fuel Pressure Port
B) Oil Pressure Port
C) Any other Pressure port
INSTALLATION
1. Locate pressure port. This gauge is designed for 1/8" NPT. In some
cases an adapter may be necessary.
2. Install T-fitting if needed to share test port with additional gauge(s).
3. Ensure the regulator is mounted with the gauge face vertical,
at the right angles to the ground, with the Vent Valve at the top.
4. Apply Teflon sealing compound to insure a leak-free connection.
5. Install gauge into pressure port, being careful not to over tighten.
6. After installation, start engine and check all connections for leaks.
OPERATION
Your gauge may be equipped with an external vent valve for the purpose of venting the gauge. Changes in temperature and environmental
pressure can affect how a liquid filled gauge reports pressure. Your new Auto Meter liquid filled gauge may be equipped with a unique vent valve
that allows gauge pressure to be equalized to atmosphere, as needed, insuring accurate pressure readings regardless of operating conditions.
To vent the gauge case push the black band back covering the vent valve head and gently lift it up slightly, DO NOT REMOVE THE VALVE.
Once the valve is raised, gauge case pressure is again equalized to atmosphere, and reported pressure will be accurate. Please push the stem
back down and replace the black retaining band immediately after equalizing pressure to reseal the gauge and help retain the valve during vehicle
operation.
NOTE: The gauge must be mounted with the gauge face vertically, (or as close to 90° to the ground as possible) with the vent on
top. This is to prevent the gauge from leaking during venting.
Vented Closed
NOTE: This liquid filled gauge is not intended to be 100% full of liquid. When held vertical, the level can appear to be between 3/4 and 7/8 full.

CAUTION: Some late model vehicles use electronic sensors in their
pressure and temperature senders for engine control functions. Before
removing the original senders, we recommend that you contact your Auto
Dealer to be sure no critical functions will be disrupted. With pressure
gauges, it is beneficial to add a T-fitting to install your new gauge and to
keep the warning light operational. This allows you to monitor the
pressure and still have a warning light to indicate emergency conditions.
