QuickCar Fuel Pressure Warning Light Kit 4 PSI 1/8 in NPT Male 61-719

Fuel pressure is a critical variable in engine performance—drop below the threshold, and you're looking at lean conditions, hesitation, and potential damage to injectors and fuel delivery components. The QuickCar Fuel Pressure Warning Light Kit gives you real-time visibility into fuel system health, alerting you the moment pressure dips below 4 PSI so you can diagnose issues before they compound. Whether you're tuning a carbureted race car or monitoring a fuel-injected build, this kit provides the data you need to keep your engine running at peak efficiency.

Installation is straightforward thanks to the included sender, wiring harness, and light unit. The 1/8-inch NPT male fitting threads directly into your fuel line or manifold, eliminating the need for adapters or custom fabrication on most applications. Simply connect the sender to the light, mount the indicator in your dash or on your vehicle's frame, and you're ready to monitor pressure in real time.
