Adjustable Tank Sender 240-33 OHM

The Adjustable Tank Sender 240-33 OHM from Classic Instruments is a precision fuel level sending unit engineered for classic and custom vehicles with tanks ranging from 6 to 24 inches in depth. As a mechanic working on fuel system retrofits and restorations, you'll recognize this component as essential for accurate gauge readings on custom fuel tanks where OEM senders no longer fit. This adjustable design eliminates guesswork when adapting modern instrumentation to non-standard tank configurations, making it indispensable for hot rodders, restorers, and performance builders who demand reliable fuel monitoring.

Built with a 240-33 ohm resistance range, this sender interfaces seamlessly with Classic Instruments gauges and most aftermarket fuel level instrumentation that follow industry-standard resistance specifications. The adjustable mechanism allows field calibration to match your specific tank depth without requiring multiple units or complex modifications—a feature that saves installation time and eliminates costly gauge inaccuracy. At 1.15 lbs and compact dimensions of 3.4 x 3.2 x 17.4 inches, the unit fits tight engine bays and custom tank installations while maintaining robust construction for long-term reliability in high-vibration environments.

This adjustable tank sender suits custom fuel tank fabrication, classic car restorations, and performance vehicle builds where OEM fuel sending units are unavailable or incompatible. Installation requires basic electrical knowledge and compatibility verification with your specific gauge or fuel level display system—cross-reference your dashboard instrumentation's ohm rating before purchase. The 240-33 ohm specification ensures compatibility with Classic Instruments fuel gauges and most quality aftermarket gauge clusters designed for traditional resistance-type senders, making it a reliable upgrade path for discerning builders.
