Sport Comp 2 1/16in Fuel 0-100 PSI Elec.

The Sport Comp 2 1/16in Fuel 0-100 PSI Electronic fuel pressure gauge from Autometer is essential equipment for any serious engine builder, tuner, or mechanic diagnosing fuel system performance. Whether you're troubleshooting a stumbling engine, validating fuel pump output during a modification, or monitoring pressure under heavy load, this gauge delivers real-time feedback that carburetor and fuel-injected platforms alike demand. Accurate fuel pressure measurement is non-negotiable when chasing horsepower or reliability—this instrument provides the precision you need to isolate fuel delivery issues before they cause expensive damage downstream.

The electronic sender unit in this gauge converts fuel pressure directly into a stable digital signal, eliminating mechanical gauge drift and providing consistent readings across the full 0–100 PSI range. The compact 1/16in diameter housing makes it a natural fit in cramped engine bays where space is tight, and the two-inch face dial is legible from the driver seat or work bench. Autometer's Sport Comp line uses durable internals designed to withstand vibration, heat, and the pulsing nature of real fuel systems, making it far more reliable than cheaper alternatives that fade or fail after extended use.

This gauge suits fuel-injected engines, high-performance carbureted builds, and supercharged or turbocharged applications where fuel pressure stability is critical to tune success. Installation requires a tee fitting at the fuel rail or pump discharge line, basic wiring to 12V power and ground, and a sender line connection—well within reach of DIY enthusiasts and professional shops alike. The 0–100 PSI range covers street engines, race applications, and diesel platforms, making it a versatile addition to any serious tuner's toolkit or diagnostic bay.
