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.

NPT port on engine. (For engines
with a
3
⁄

"
NPT port use Auto Meter adapter no. 2263). Insert temperature
sensing bulb in the mounting nut and carefully tighten sealing nut, while holding
mounting nut. The Oil Temperature gauge usually requires drilling a hole and
welding the Auto Meter no. 2261 steel weld fitting in the oil pan. Be sure to
check for adequate internal clearances for the temperature sensing bulb. Install
temperature sensing bulb as described above.
4. Make sure gauge tubing is free from hazard of moving parts or hot engine
components.
5. Start engine and thoroughly inspect installation for any leaks.
6. Twist in light socket assembly and connect one wire to dash lighting circuit or
other 12V power source and the other wire to a good ground.

Venting for Liquid Filled gauges Only
Auto Meter’s Pro Comp Liquid Filled Gauges are equipped with a vent screw on the top of the
case. Internal case pressure can change due to altitude, barometric pressure, and temperature,
causing an inaccurate or “off zero” reading on more sensitive low pressure gauges such as 0-15
psi fuel pressure, vacuum, boost, and vacuum/boost gauges. To prevent this it is recommended
that the gauge be vented.
With the vent screw in the upright position, turn the screw two turns counterclockwise to equalize
the gauge case pressure. This allows the gauge to breathe and self adjust.
Note on Ultra-Nite (glow In The Dark)
The glow in the dark coating on the dial of the Ultra-nite gauge may turn gray if exposed to direct sunlight for extended periods of time. When the car is not being used
and will be in direct sunlight for long periods of time, place the provided red plastic cover on the gauge.
The Ultimate LED Lighting Upgrade
Available through your local speed shop or favorite Auto meter dealer, these intense LED bulbs simply replace the standard 161, 168, 193, or 194 light bulbs used in most
Auto meter gauges, tachometers, and speedometers. Smaller LED bulbs are available for tachometers that feature the small “twist in” light on the front tachometer.
LED Replacement Kits are sold one per package.
