Restore Accurate Fuel Gauge Readings with OE-Style Sending Unit

A faulty fuel gauge often traces back to a worn or inaccurate fuel tank sending unit. This OE-style fuel tank sender restores your Corvette’s ability to provide consistent, reliable readings. Designed for 1978–1981 models, this assembly features a 90-ohm resistance range and includes the strainer and mounting seal—a necessary upgrade since the original units used the tank bladder as a gasket. This complete unit mounts inside the tank and connects to the factory fuel pickup and gauge wiring.
