AutoMeter 2174 Auto Gage 1-1/2 in. Direct Mount Pressure Gauge 0-100 PSI Liquid

Vehicle Fitment

Universal - no vehicle-specific fitment. Compatible with any 12V automotive, motorcycle, marine, or racing application with a 1/8 in. NPTF male port.

Fitment Notes

• Direct mount gauge - threads directly onto a 1/8 in. NPTF male fitting at the pressure source. No remote line or sender required.
• Intended for under-hood or chassis-mounted use where vibration, heat, and the elements are present - liquid-filled design is recommended for these environments.
• Gauge reads 0-100 PSI - suitable for oil pressure, fuel pressure (EFI and high-pressure carbureted), and air/boost pressure monitoring.
• No electrical system required for operation.

Features

• Liquid-filled design dampens needle movement for smooth, steady readings in high-vibration environments such as direct engine or chassis mounting.
• Bronze Bourdon tube mechanical movement with 270-degree full-sweep dial for precise pressure readings without the need for electrical power or a sender.
• 1/8 in. NPTF male fitting on the back of the gauge threads directly into the pressure source for fast, leak-free installation.
• Compact 1-1/2 in. diameter is ideal for tight spaces such as fuel rails, oil galleys, carburetors, and remote mounting brackets.
• Black dial face with fluorescent red pointer for quick, at-a-glance readings in bright and low-light conditions.
• Highly polished chrome bezel provides a clean, finished appearance in any engine bay or chassis application.

Product Description

The AutoMeter 2174 is a 1-1/2 in. direct mount liquid-filled mechanical pressure gauge from the Auto Gage series, reading 0-100 PSI via a 1/8 in. NPTF male fitting that threads directly into the pressure source. The liquid-filled case dampens needle bounce caused by vibration, pulsation, and pressure spikes - making it well-suited for direct mounting on oil passages, EFI fuel rails, or remote chassis brackets where a standard dry gauge would be difficult to read or prone to damage. No electrical system or sender is required.

The compact 1-1/2 in. diameter fits tight spaces where larger gauges won't, and the 270-degree full-sweep bronze Bourdon tube movement delivers accurate, repeatable pressure indication across the full 0-100 PSI range. The black dial with fluorescent red pointer and polished chrome bezel give it a clean appearance suitable for street cars, weekend racers, motorcycles, and off-road builds. For the same gauge in a 0-60 PSI range, see AutoMeter part #2173. For a white dial version at 0-100 PSI, see AutoMeter part #2177.
