8in 240-33 OHM Sender

The 8in 240-33 OHM Sender from JAZ is a precision fuel level sending unit designed for serious engine builders, restoration specialists, and performance mechanics who demand accuracy in fuel system diagnostics. This 8-inch probe sending unit is essential for vehicles equipped with custom fuel tanks, fuel cell installations, or original equipment requiring replacement senders that maintain proper ohm resistance calibration. Whether you're retrofitting a classic hot rod, tuning a street-legal performance build, or diagnosing fuel gauge problems in a modified vehicle, this sender provides the electrical consistency needed for reliable fuel level readouts.

The 240-33 ohm resistance range is the critical specification that ensures proper gauge needle response across the fuel tank's empty-to-full spectrum. The 8-inch probe length accommodates mid-sized fuel tanks and custom installations where standard shorter units fall short, literally and functionally. JAZ sending units are engineered with sealed float mechanisms and stainless-steel components that resist corrosion from fuel additives and ethanol blends, ensuring long-term measurement stability. The compact 3.4 x 3.3-inch mounting footprint allows integration into tight tank configurations without excessive modification, while the overall 14.7-inch assembly length—including probe and connector—gives installers flexibility in tank-bottom placement.

Mechanics and enthusiasts working with fuel cell manufacturers, custom tank builders, or vehicles requiring aftermarket fuel system conversions will find this sender indispensable for maintaining gauge accuracy without custom calibration headaches. The 240-33 ohm specification is compatible with most traditional fuel gauge circuits found in American muscle cars, street rods, and modern performance vehicles using standard dash instruments. Installation requires only basic electrical knowledge—connect the sender output to your gauge circuit, secure the mounting flange, and the resistance characteristics will immediately provide proportional fuel level indication. Weighing just 0.9 lbs, this sender adds minimal complexity while delivering the precision fuel monitoring that separates amateur guesswork from professional-grade vehicle diagnostics.
