This mechanical 1-1/2” (38mm) 100 PSI Chevy TBI Fuel Pressure Gauge doesn’t require a power source or wiring. It threads into the fuel system with a 1/8-27 NPT Male Thread located on the back. Take readings from 0 to 100 PSI and catch any unusual pressure dips or spikes.
In addition to getting accurate readouts, each GM TBI Fuel Pressure Gauge will look great in your Chevy. It has a black analog dial with a white needle and clear lens, all housed in a waterproof chrome body with a trim ring. The gauge is liquid filled with silicone oil to help protect the needle from engine vibrations.
We made the LS Fuel Pressure Gauge Adapter specifically for Chevrolet GM Engines. Install a 1/8-27 NPT fuel pressure sender or a direct-mount gauge without major modifications and avoid removing the Schrader Valve. It includes a 1/8" NPT Female to Male 90 Degree Elbow and a -4 AN Fuel Rail Adapter fitting.
