Auto Meter Full Sweep Electric Pressure Gauges Instruction Manual

Auto Meter Full Sweep Electric Pressure Gauges

Use Teflon sealing compound sparingly where the symbol indicates. (Tape is not recommended on these threads.)

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.

Overview

Fuel & Oil Pressure

WARNING:
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 25⁄8” hole for 25⁄8” gauges, and a 21⁄16” hole for 21⁄16” gauges. Use supplied brackets and nuts to secure the gauge to the dash.
4. Drill 1” diameter hole where wires pass through sheet metal (such as a firewall) and install the rubber grommet provided. (Grommet will require slit.)
5. Connect the white wire to the dash lighting or switchable 12v light source, the red wire to the switch +12V source, and the black wire to the ground. (see diagram for details).
6. [For oil pressure gauge installation, an optional 1⁄4” NPT adapter is included. For the fuel pressure gauge, install the 1⁄8” NPT pressure 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 the 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 remotely mounted to either the fender well 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 the vehicle and/or operator injury. Braided stainless steel lines are sold separately by Auto Meter, and can be used to accomplish this.
7. Reconnect the 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 it. Do not operate a 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.

ATTENTION DODGE DIESEL OWNERS:
If using on ‘98-’02 (some ‘03) Cummins diesels, you MUST use #3227 Line Kit and #3279 restrictor to prevent premature failure of the sender. Failure to do so will void the warranty.

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

Nitrous Pressure

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 25⁄8” hole for 25⁄8” gauges, and a 21⁄16” hole for 21⁄16” gauges. Use supplied brackets and nuts to secure the gauge to dash.
4. Drill 1” diameter hole where wires pass through sheet metal (such as a firewall) and install the rubber grommet provided.
5. Connect the white wire to dash lighting or switchable 12v light source, the red wire to switch +12V source and the black wire to the ground. (see diagram for details)
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 (e.g. NOS part #16770 or #16771) either on the nitrous bottle or nitrous solenoid. Re-install the main nitrous feed line. Install pressure sender and wiring harness. For mounting off the bottle in rear of the 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.

Brake Pressure

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 25⁄8” hole for 25⁄8” gauges, and a 21⁄16” hole for 21⁄16” gauges. Use supplied brackets and nuts to secure the gauge to the dash.
4. Drill 1” diameter hole where wires pass through sheet metal (such as a firewall) and install the rubber grommet provided.
5. Connect the white wire to the dash lighting or switchable 12V light source, the red wire to the switch +12V source, and the black wire to the ground. (see diagram for details)
6. If you are not familiar with proper brake system bleeding procedures, do not install this gauge. Have a qualified mechanic do it for you.
7. Locate a 1⁄8”-27 NPT port in your brake system in a location where you would like to measure brake pressure. If no port is available, you will need to install a tee fitting in the brake line you want to measure. Only use fittings that are approved for use in brake systems.
8. Install the pressure sensor in the 1⁄8”-27 NPT port using a Teflon thread sealing compound.
9. Bleed the brake system using standard brake bleeding procedures. Again, if you are not familiar with proper brake system bleeding procedures, do not install this gauge. Have a qualified mechanic do it for you.

Note: Install the sensor with the electrical connector facing down to allow any air in the sensor to escape during bleeding.

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.
