Complete stand alone gauge requires no additional sensors or programs to operate * Ideal for both fuel injected and carbureted motors * LED displays provide precise reference to critical operating conditions and alert driver of potentially damaging operating conditions * Includes 0-5V analog output for routing to engine management system or data logger * Easy to read faceplates/displays are designed to complement existing AEM gauge styles * Included bezels and face plates allow you to personalize the look of your gauge
Why This Gauge Matters
Oil and fuel pressure are two of the most critical safety parameters in any performance vehicle.
This gauge helps prevent:
-
Lean conditions from fuel pressure drops
-
Rod bearing damage from low oil pressure
-
Turbocharger oiling failures
-
Fuel pump cavitation
-
Injector starvation
-
High-RPM lubrication collapse
The 30-0301 gives instant warning before damage happens.
Ideal Uses
-
Turbo builds (single, twin, big turbo, OEM+)
-
High-flow E85 fuel systems
-
Track and road-race engines
-
Drift cars with high lateral G-force oiling demands
-
Drag builds needing precise pressure control
-
Daily-driven performance cars
Installation Notes
-
Requires compatible AEM 0–100 PSI or 7 BAR pressure sensor
-
For oil pressure: use a remote sensor line (never mount sensor directly to block)
-
Keep wiring away from turbo manifolds/exhaust
-
Wire analog output to ECU for real-time logging
-
Standard 52mm installation
Typical install time: 30–60 minutes.
Final Verdict
The AEM 30-0301 X-Series 100 PSI Pressure Gauge with White Face Kit is one of the most accurate and reliable digital pressure monitors available.
It combines X-Series speed, modern electronics, and a classic white-face look — making it perfect for serious builds that demand both performance and clean aesthetics.
If you need precise oil or fuel pressure monitoring, this gauge is the one to run.
