where symbol indicates. (Tape not
recommended on these threads.)

OPTIONAL SLIT TUBING RECOMMENDED

(AVAILABLE AT MOST HARDWARE STORES)

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® # 312 001 or an equivalent).

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

1

for 2

⁄16" 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.
(see diagram for details)

WARNING: Not compatible with Nitromethane, Methanol,
or 100% MTBE.

sender into the fuel system (See caution below). 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.

CAUTION:

If you will be working with the fuel system, take care to insure no sparks
or flames occur. Do not smoke while installing the fuel pressure sender.

Power-Up

The pointer will move counter clockwise to the stop pin and then moves to the current gauge reading. 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.

Peak Recall

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

Full Dial Warning

This gauge features full dial warning. When a warning point is reached, the entire dial illuminates in the programmed warning color. This feature
is available for both a high and low warning set point. In addition, the warning color will flash when an over warn point is reached.

Pro Control High Warning Set Point

To adjust the high warning set point, press and release the WARN button. The warning light will begin to flash and the pointer will move to the
previous high warning set point signifying that warning set mode has been selected. Once in set mode, press the WARN button to move the
pointer down, or press the PEAK button to move the pointer up. Three seconds after the last button press, the warning light will stop blinking
and the pointer will return to the current reading. The warning set points are retained when power is removed from the gauge.

Pro Control High Over Warn Set Point

To adjust the high over warn set point, press and hold the WARN button. After three seconds the warning light will begin to flash and the
pointer will move to the previous high over warning set point signifying that over warn set mode has been selected. Release the warn button.
Once in set mode, press the WARN button to move the pointer down, or press the PEAK button to move the pointer up. Three seconds after
the last button press, the warning light will stop blinking and the pointer will return to the current reading. The over warn set points are retained
when power is removed from the gauge.

Pro Control Low Warning Set Point

To adjust the low warning set point, press and hold the WARN button, and while still holding the WARN button, press and release the PEAK
button. The warning light will begin to flash and the pointer will move to the previous low warning set point signifying that warning set mode has
been selected. Once in set mode, press the WARN button to move the pointer down, or press the PEAK button to move the pointer up. Three
seconds after the last button press, the warning light will stop blinking and the pointer will return to the current reading. The warning set points
are retained when power is removed from the gauge.

Pro Control Low Over Warn Set Point

To adjust the low over warn set point, press and hold the WARN button, and while still holding the WARN button, immediately press and hold
the PEAK button. After three seconds the warning light will begin to flash and the pointer will move to the previous low over warning set point
signifying that over warn set mode has been selected. Release both buttons. Once in set mode, press the WARN button to move the pointer
down, or press the PEAK button to move the pointer up. Three seconds after the last button press, the warning light will stop blinking and the
pointer will return to the current reading. The over warn set points are retained when power is removed from the gauge.

Change Backlight Color

To change the backlight color:

With power off, press and hold the warning button. Apply power to the gauge. Release the WARN button. Press and release the PEAK button.
The pointer will move to half scale and the dial will illuminate with the current Backlight Color. Press and hold the PEAK button to cycle through
the available colors. Once you have selected the desired color, release PEAK and don’t press any buttons for about three seconds. The dial
will flicker white several times to indicate the desired setting has been saved and the gauge will return to normal operation with your new color
selection. Color selections are saved when power is off.

Change Low Warn Color

(Region A color)

Warn Color Set Mode:

With power off, press and hold the WARN button. Apply power to the gauge. Release the WARN button. The pointer will be at the stop pin and
the dial illumination will be off. Press and release the WARN button to cycle between HIGH warn color set and LOW warn color set modes. In
High Warn color set mode, the pointer will move to full scale and the dial will illuminate with the current High Warn color. In Low Warn color set
mode, the pointer moves to the minimum position and the dial will illuminate with the current Low Warn color.

To change Low Warn Color:

When the Low Warn color set mode has been selected (see above), press and HOLD the WARN button to cycle through the available colors.
Once you have selected the desired color, release the WARN button. Don’t press any buttons for about three seconds. The dial will flicker
white several times to indicate the desired setting has been saved and the gauge will return to normal operation with your new Low Warn color
selection. Color selections are saved when power is off.

Change High Warn Color

(Region C color)

Warn Color Set Mode:

With power off, press and hold the WARN button. Apply power to the gauge. Release the WARN button. The pointer will be at the stop pin and
the dial illumination will be off. Press and release the WARN button to cycle between HIGH warn color set and LOW warn color set modes. In
High warn color set mode, the pointer will move to full scale and the dial will illuminate with the current High Warn color. In Low Warn color set
mode, the pointer moves to the minimum position and the dial will illuminate with the current Low Warn color.

To change High Warn Color:

When the High Warn color set mode has been selected (see above), press and hold the WARN button to cycle through the available colors.
Once you have selected the desired color, release the WARN button. Don’t press any buttons for about three seconds. The dial will flicker
white several times to indicate the desired setting has been saved and the gauge will return to normal operation with your new High Warn color
selection. Color selections are saved when power is off.
