CAUTION!

As a safety precaution, the
+12V terminal of this product
should be fused before
connecting to the 12V ignition
switch. We recommend using
a 1 Amp, 3AG fast-acting type
cartridge fuse (Littlefuse

NOTE: When the ignition is off the pointer may not
always rest at zero.

Installation - Fuel & Oil Pressure

The fuel system is pressurized and often retains this pressure for an
extended period of time. Properly vent your fuel system before installing
the fuel pressure sender. If you are not familiar with the proper method
of venting, you MUST have this done by an experienced mechanic.

1. Check that you have all parts required for installation, and the
engine is cool.

2. Disconnect the negative (-) battery cable.

3. Gauge mounts in a 2
gauges. Use supplied brackets and nuts to secure gauge to dash.

4. Drill 1” diameter hole where wires pass through sheet metal
(such as firewall) and install rubber grommet provided.
(Grommet will require slit.)

5. Connect the white wire to dash lighting or switchable 12v light source,
the red wire to switched +12V source and the black wire to ground.

6. [For oil pressure gauge installation, an optional
included. For fuel pressure gauge, install the
into the fuel system (See warning in next column). For Ford fuel injected
applications with a Schrader valve in the fuel rail, use adapter 3280
between the fuel rail and pressure sender.]
If unit is to be installed on a high vibration application such as a full race
engine or engine capable of high RPM, it is strongly recommended that
the sender be remote mounted to either the fenderwell or firewall, to
insulate from vibration. Failure to remote-locate pressure senders on

such an application could result in gauge failure and potential
damage to vehicle and/or operator injury. Braided stainless steel lines

are sold separately by Auto Meter, and can be used to accomplish this.

7. Reconnect negative (-) battery cable.

NOTE: Test all fittings and hoses for any leakage. If any leaks are detected,
determine the cause of the leak and repair. Do not operate vehicle if
any leaks are detected.

6. Make sure the nitrous bottle valve is closed and there is no

pressure in the system.

7. Remove the main nitrous feed line from the bottle or the nitrous
solenoid. Install the in-line gauge adapter either on the nitrous
bottle or nitrous solenoid. Re-install the main nitrous feed line.
Install pressure sender and wiring harness. For mounting off bottle
in rear of car, use 20’ sender harness model 5223.

8. Open the nitrous bottle valve.
NOTE: Test all fittings and hoses for any leakage. If any leaks are
detected, determine the cause of the leak and repair. Do not
operate vehicle if any leaks are detected.

Power-Up

The pointer will move backward to the stop pin and then move to the zero box. This procedure is an auto-calibration
function and is performed on every power-up. While this test is being performed, the gauge may make a clicking sound.
This is normal.

Warning Indicator

To adjust the warning set point, momentarily press & release the WARN (W) button. The warning light will begin to flash and the pointer will move to the
previous set point signifying that warning set mode has been selected. Once in set mode, press the WARN (W) button to move the pointer down, or press
the PEAK (P) button to move the pointer up. Warning set points can only be set in the pressure range. Three seconds after the last button press, the
warning light will stop blinking & the pointer will return to the current pressure reading. The warning set point is retained when power is removed
from the gauge.

Peak Recall

Press and hold the PEAK (P) button to recall the highest pressure reading since the memory was last cleared. To clear the memory, press & hold the PEAK
(P) button, and while still holding the PEAK (P) button, press the WARN (W) button. The pointer will move to 0 psi to indicate that the memory has been
cleared. Release the PEAK (P) & WARN (W) buttons to resume normal operation. The peak recall point is retained when power is removed from the gauge.
