The AutoMeter Spek-Pro 2-1/16 Fuel Pressure Gauge with Peak Memory is a precision analog fuel pressure monitoring instrument designed for engine diagnostics and performance verification. This electric gauge delivers real-time fuel system pressure readings across a 0–15 psi range, making it essential for tuning, troubleshooting, and validating fuel delivery integrity on naturally aspirated and forced-induction platforms.
The 2-1/16-inch dial with full-sweep needle movement provides immediate visual feedback during throttle application and load changes. The peak memory function captures and retains the highest pressure reading during a test cycle, eliminating the need for constant gauge observation and allowing technicians to identify pressure spikes, drops, or anomalies after the fact. The black face with high-contrast markings ensures readability in variable lighting conditions common in shop and field environments. The compact 4.9 x 4.5 x 5-inch footprint accommodates installation in tight dash or console spaces without compromising functionality or ergonomics.
This gauge serves mechanics, engine builders, tuners, and powersports enthusiasts diagnosing fuel pump performance, regulator operation, injector supply consistency, and system-level pressure stability. The 0–15 psi range is calibrated for naturally aspirated gasoline engines and carbureted applications where lower fuel pressures are the norm. Technicians use peak memory capability to verify that fuel pressure holds steady during acceleration, detects regulator creep, or identifies pump cavitation under sustained load. The electric operation eliminates mechanical line routing and simplifies installation in modern vehicle architectures.
AutoMeter's Spek-Pro line balances professional-grade accuracy with cost-effective manufacturing, positioning this gauge as a preferred choice for independent shops and serious hobbyists. The analog full-sweep design avoids digital lag and battery dependency, delivering instantaneous response to pressure transients that digital displays may miss or misinterpret. Weight of 0.86 lbs and standard mounting provisions make integration straightforward across both vintage and contemporary platforms.
