Venting liquid filled gauges
Autometer's liquid filled gauges have a vent screw on top of the gauge's housing. Internal pressure can change because of altitude, barometric pressure, or temperature. This causes an inaccurate or off zero reading on more sensitive low pressure gauges. To prevent this, it's 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. Then re-tighten the screw.Do NOT over tighten the vent screw! Over tightening the screw WILL damage the threads of the gauge's housing.
This gauge includes 6 feet of capillary tubing. You CAN NOT shorten the tubing! It is filled with ether gas. When the gas expands, the needle on the gauge rises.
Autometer's mechanical radiator coolant temperature gauges include the 2273 1/2" NPT pipe thread adapter fitting. Towards the top edge of the probe, there's a tapered seat that gets compressed between the 2273 adapter fitting and the 5/8-18 tube nut (usually blue).
