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

Installation - Fuel & Oil 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 for 2
1
⁄16” gauges, and a 2
5
⁄8” hole for 2
5
⁄8”
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)
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.
NOTE: When the ignition is off the pointer may not
always rest at zero.
WARNING: Not compatible with Nitromethane, Methanol,
or 100% MTBE.
6. [For oil pressure gauge installation, an optional
1
⁄4” NPT adapter is
included. 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.
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.
