    All engines

Intended for compatible 1968–1970 Chevrolet Chevelle applications. Confirm the vehicle requires a 3/8-inch main fuel line. Verify that the original system uses a 2-line configuration. The second line may serve a return or vent function depending on the exact application. Confirm fuel-tank design and sender mounting-flange pattern. Verify sender resistance range is compatible with the vehicle’s fuel gauge. Check pickup-tube depth against the fuel tank. Confirm float-arm travel and clearance inside the tank. Verify lock-ring and seal dimensions. Fuel tanks from different years or aftermarket manufacturers may use different sender openings. Modified fuel systems, electric pumps, EFI conversions, or custom return systems may require different line sizes or configurations. Do not assume lock ring, gasket, strainer, or wiring connector are included. Compare the original sender assembly before installation.
