Fuel Tank Sending Unit 0-90 Ohms

The Fuel Tank Sending Unit 0-90 Ohms from CLASSIC INSTRUMENTS is an essential component that connects your fuel tank to your dashboard fuel gauge, converting the physical fuel level into electrical resistance for accurate readings. This unit is ideal for anyone restoring a classic car, upgrading a custom build, or replacing a faulty sender in a daily driver.

Operating on a 0–90 ohms resistance curve, this sending unit is designed for classic and street-rod fuel gauges that require linear resistance output throughout the float's travel. The float arm pivots with the fuel level, adjusting a precision resistor that changes electrical resistance accordingly—approximately 90 ohms when empty and near 0 ohms when full. CLASSIC INSTRUMENTS has engineered this sender for reliability, featuring robust internal contacts and a sealed float chamber to resist fuel permeation and electrical corrosion.

Mechanics and automotive enthusiasts installing classic instruments fuel gauges, retrofit gauge clusters, or custom dashboard setups will find this sending unit indispensable for ensuring accurate fuel measurement. Its compact and lightweight design allows for easy installation in most fuel tank mounting plates without excessive bulk or complexity.
