RedLine Gauge 2-1/16in Fuel Pressure 0-100psi

The RedLine Gauge 2-1/16in Fuel Pressure 0-100psi from QUICKCAR RACING PRODUCTS is an essential instrument for serious engine builders, performance tuners, and race-prepped vehicles requiring accurate real-time fuel system monitoring. Whether you're running a naturally aspirated street engine or a boosted competition platform, this analog fuel pressure gauge delivers the precision feedback needed to optimize carburetor tuning, fuel injection calibration, and fuel pump performance. Proper fuel pressure monitoring is non-negotiable when diagnosing fuel delivery issues, verifying regulator function, or validating modifications that demand consistent system pressure under varying load conditions.

This 2-1/16-inch analog gauge features a 0-100 psi range, making it suitable for both carbureted and fuel-injected applications operating at typical street and moderate performance pressures. The RedLine design utilizes a mechanical needle movement driven by direct fuel line connection, eliminating electronic dependencies and providing instantaneous response to pressure fluctuations during acceleration, idle transitions, and load changes. The compact 2-1/16-inch diameter allows flexible dashboard mounting or pod installation without excessive space requirements, while the clear face markings ensure visibility even during high-intensity driving or competitive events.

This gauge benefits engine builders troubleshooting lean-running conditions, carburetor enthusiasts fine-tuning float bowl levels, and fuel-injected platform owners verifying regulator response under boost or load. Installation requires standard 1/8-inch NPT fuel line connection to the fuel rail or pressure point downstream of the pump and regulator; always include a restrictor fitting to prevent gauge damage from transient spikes. The 0-100 psi range covers carbureted vehicles (typically 4-7 psi), street EFI engines (35-45 psi), and boosted applications demanding higher baseline pressures—making it a versatile addition to any serious mechanic's diagnostic toolkit.
