Fuel Probe Capacitance Type 4in-12in

The Fuel Probe Capacitance Type 4in-12in by ATL FUEL CELLS is an essential instrument for serious motorsports enthusiasts and professional mechanics managing custom fuel system builds. This capacitance-type fuel level sensor delivers real-time, accurate fuel quantity data to engine management systems, data loggers, and custom gauges—critical information when tuning high-performance applications, endurance racing, or complex fuel cell installations where traditional float-based senders fall short.

Capacitance-type fuel probes measure fuel level by detecting changes in electrical capacitance as the dielectric constant shifts between air and fuel inside the tank. Unlike mechanical floats, this technology eliminates moving parts, corrosion, and calibration drift—hallmarks of reliability in extreme motorsports environments. The Fuel Probe Capacitance Type 4in-12in accommodates fuel tank depths ranging from 4 to 12 inches, making it adaptable to a wide range of custom fabrications and aftermarket fuel cell configurations.

Its compact 13.2-inch overall length and lightweight construction of 0.5 lbs simplify integration into tight engine bays and specialized fuel system layouts without adding unnecessary mass or complexity to your platform. Professional racers, fuel cell manufacturers, and vehicle builders will find this probe invaluable for precision fuel management in their high-performance applications.
