or an equivalent).
Installation - Fuel & Boost 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
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.
WARNING: Not compatible with Nitromethane, Methanol,
or 100% MTBE.

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.
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.
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
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.

As a safety precaution, the +12V
terminal of this product should be

ignition switch. We recommend
using a 1 Amp, 3AG fast-acting type
cartridge fuse (Littlefuse

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.
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 nuts to secure gauge to dash.
4 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

5. Install sender into pressure port of appropriate type. If unit is

If not, or if remote relocation of sender is required, a ground

6. Route the violet wire through the firewall. If a new hole is drilled in
the firewall, a gromet is recomended. Connect the violet wire to the
terminal post on the pressure sender.
7. Reconnect negative (-) battery cable.
NOTE:
Test all fittings and connections for leaks. If any leaks are
detected, Determine the cause of the leak and repair.
Do not operate vehicle if any leaks are detected.
Caution: LUBRIPLATE® DS-ES is a non-hazardous substance.
However, it is recommended to wash hands thoroughly after use.
NOTE: Do not remove factory temp sender to install temp sender. If no
location found, a hose adapter can be used.
Sender Error
If no sender is connected, the gauge will display “EØ”. Approximately 4 seconds after the sender is connected, the gauge will display the
fuel level and resume normal operation. If sender is hooked up and “EØ” is displayed, check sender for improper ground or open circuit.
Power-Up
When power is applied to the gauge, the display will light up with all eights immediately followed by the gauge firmware version. After the
firmware version is momentarily displayed, the gauge will begin normal operation and display real time sender readings.
