2-1/16 U/L Fuel Press Gauge 0-100psi

The AutoMeter 2-1/16" Ultra-Lite Fuel Pressure Gauge 0-100 psi (Model 4371) is a precision analog instrument designed for real-time fuel system monitoring in high-performance and racing applications. This electric fuel pressure gauge delivers full-sweep response with a silver face that provides excellent visibility in cockpit and engine bay environments. The compact 2-1/16-inch diameter fits standard gauge clusters and aftermarket installations where space is limited, making it the go-to choice for engine builders, tuners, and serious enthusiasts who demand accurate fuel pressure feedback during dyno testing, track runs, and street performance driving.

The 0-100 psi range covers the spectrum of typical fuel system pressures from carbureted engines through modern EFI platforms, providing direct visibility into fuel pump operation and regulator function. An electric sender signal delivers needle response across the full sweep, eliminating lag and giving operators immediate confirmation of pressure changes under load. The Ultra-Lite construction keeps overall gauge weight to 0.76 lbs, a critical consideration in weight-conscious builds where cumulative ounces impact performance. Silver-faced analog gauges remain the industry standard for reliability and legibility—no digital screens to fail, no complexity to troubleshoot.

This gauge is built for tuners, drag racers, street performance builders, and anyone running a modified fuel system who needs unambiguous pressure confirmation. Whether monitoring a carbureted small block, a turbocharged four-cylinder, or a fuel-injected V8, the 4371 provides the precision feedback required to optimize jetting, verify pump capacity, and diagnose fuel delivery issues quickly. Its compact footprint and proven AutoMeter design make it a standard choice in shop environments and competition paddocks where reliability and accuracy are non-negotiable.
