Preliminary Steps
1. Read instructions thoroughly. The installation of this product
requires the expertise of a trained automotive mechanic. Please
consult a qualified mechanic if you have not had training in the
proper installation of instruments.
2. Determine ideal mounting location. Choose a location that will not
obstruct visibility or impair driving. Consult your vehicle’s repair
manual to locate:
A. Water temperature port
B. 12V ignition switch or fuse box
C. Oil pressure port
3. Consult your vehicle’s manual to determine the best route for
tubing to follow. Choose a path free from hazard of moving parts
or hot engine components.
4. Assemble tools and parts required for installation.
5. Disconnect negative (-) battery cable. Do not allow cable to touch
battery or any metal.
NOTE: Disconnecting battery ground may require you to re-
program your radio station and clock after re-connection.
6. Hole panel in desired mounting location and use as a template to
mark drill holes on the underside of dash.
7. Drill holes with an
1
⁄8” drill bit and mount bracket under dash using
self-tapping screws and flat washers provided.
CAUTION: Some late model vehicles use electronic sensors
in their pressure and temperature senders for engine control
functions. Before removing the original senders, we recommend
that you contact your Auto Dealer to be sure no critical functions
will be disrupted.
• With pressure gauges, it is beneficial to add a T-fitting to install
your new gauge and to keep the warning light operational. This
allows you to monitor the pressure and still have a warning light
to indicate emergency conditions.
Important Assembly Procedures To Follow
1. Tighten nuts and lock washer that secure the gauge mounting
bracket. Be sure they are not so tight as to bend or distort
mounting bracket.
2. Electrical Connections
Install additional wiring and hardware as shown in diagrams
below. Now tighten the outer nut while holding the inner nut. This
is the only correct procedure and must be followed to insure safe
electrical connections. This applies to both the gauge and sender
connections.
3. Make sure wires are not rubbing against metal or each other.
NOTE: Install gauges when engine is cool.
Oil Pressure
1. Drill a
3
⁄8” dia. hole in the firewall. Install a rubber grommet
provided in firewall to insulate tubing where it passes through
sheet metal.
2. Remove existing oil pressure sender. (For computerized vehicles,
see caution in Preliminary Steps.) Install
1
⁄8” NPT adapter with
7
⁄16”
open-end wrench in this location using sealing compound on pipe
threads. If
1
⁄4” NPT adapter is needed, install it first with
9
⁄16” open-
end wrench. Be sure to hold
1
⁄4” adapter while tightening
1
⁄8” NPT
tube connector firmly with
7
⁄16” open-end wrench.
3. To help prevent leaks, be sure the end of nylon tubing with
threads toward end of tube. Next, slide ferrule onto end of tubing,
leaving
3
⁄16” between ferrule and end of tube. Insert end of tubing
into the
1
⁄8” NPT tube connector. Apply pressure to maintain
constant bond between end of tubing and inside of connector.
Slide ferrule into the adapter and then thread compression nut
on next. Tighten compression nut (with
3
⁄8” open wrench) while
holding adapter firm (with
7
⁄16” open-end wrench). This should form
a tight seal between the end of tubing and the inside of adapter.
To make sure it is a snug fit, tug lightly on the nylon tubing to be
certain it does not come out.
4. Route tubing through small grommet in firewall and cut to meet
mounted panel (leave one foot extra length before cutting).
Try to avoid potential hazard of moving parts or hot engine
components.
5. Secure gauge in mounted panel using U-bracket.
6. Slide compression nut and ferrule on this end of tubing and
tighten in the same manner described in step 3. (Use
9
⁄16” and
3
⁄8”
open-end wrenches.)
See final procedures to complete installation.
