Use teflon sealing compound sparingly
where symbol indicates. (Tape 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).
Installation - 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 2
1 ⁄
16 " hole. 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.
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) Digital display will dim when
power is applied to white wire.
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 on 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.

FIREWALL
Installation - Fuel & Boost 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 2 1 ⁄
16 " hole. 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) Digital display will dim when power is applied
to white wire.
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.
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.
WARNING: Not compatible with Nitromethane, Methanol,
or 100% MTBE.
6. For fuel pressure gauge, install the 1 ⁄
8 " NPT pressure sender 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.
8. 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.
OPTIONAL SLIT TUBING RECOMMENDED
