Some more info about the AEM 0-100 PSI Oil Pressure Gauge
AEM’s Digital Fuel Pressure Gauge unites unsurpassed accuracy, speed and control with an easy to read, digital LED interface. AEM digital gauges also offer a 0-5v analog output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC.
The AEM 100PSI Fuel Pressure Gauge has a bright LED display that shows fuel pressure in 1 PSI increments, and a sweeping LED "needle" that lines the edge and changes color as fuel pressure changes from 0 to 100. This is perfect for those who need to know fuel pressure at high RPM on tuned engines - and now you'll be able to see and log to the exact PSI. Each gauge includes interchangable silver and black bezels and black and white faceplates to personalize the look of your gauge - it's like having 4 gauges in 1!
