If after completely reading these instructions you have questions regarding the operation or installation of your instrument(s),
please contact Auto Meter Technical Service at 815-899-0801. You may also email us at service@autometer.com.

Mounting
These gauges can be mounted in a 2 1⁄16" dia. hole or in a standard
aftermarket street rod panel. Fasten with brackets supplied as shown.
(Hookup wire is required.) To assure proper functioning of this instrument, please read instructions thoroughly before installing.
NOTE: Some late model vehicles use electronic sensors in their
pressure and temperature senders for engine control functions. Before removing the original sender, we recommend
that you contact your automotive 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.
Fuel Level
1. Disconnect negative (-) battery cable.
2. Gauge connects to fuel sender on fuel tank. Existing wires may be
used, or route proper length of 18 gauge, 2 conductor wire from
fuel tank to gauge. Connect one end to terminal post on fuel level
sender and the opposite end to the sender (S) terminal spade on
back of gauge. See illustration at right.
3. Connect wire from center terminal spade on back of gauge GND (-)
to ground on fuel tank.
4. Connect wire from ignition switch to the positive I (+) wire on the
back of gauge. See figure above.
5. Install light in back of gauge and connect one wire to dash lighting
circuit or to other 12V power source and connect other wire to (-)
negative ground.
6. Reconnect negative (-) battery cable.
