The AEM 30-4401 Digital Oil or Fuel Pressure Gauge provides clear, real-time monitoring for oil or fuel pressure in performance and street-driven vehicles. Its 0-100 PSI measurement range is well suited for monitoring pressure at high engine speeds, including tuned engines and applications using carbureted or electronic fuel-injected systems. The gauge features a three-digit center readout and 24 green LED display lights for quick reference while driving.

Integrated 0-5V analog output allows the AEM 30-4401 to connect with data loggers and many engine management systems, including the AEM Infinity ECU, Series 2 EMS, and AQ-1 Data Logger. This capability makes it possible to monitor and record pressure data alongside other engine parameters. An included brass pressure sensor and plug-and-play wiring harness simplify installation, while automatic dimming adjusts the gauge face and readout lighting for improved visibility in changing conditions.

The standard 52mm, or 2-1/16-inch, gauge housing is designed for common automotive gauge installations. The interchangeable black and silver bezels, along with black and white faceplates, allow the appearance to be customized to match the vehicle interior. The box includes the AEM digital pressure gauge, pressure sensor, plug-and-play harness, interchangeable bezels, interchangeable faceplates, and installation components. Verify vehicle application, sensor port requirements, and compatibility with the selected engine management or data-logging system before installation.
