Standard Motor Products LSF139 Fuel Level Sensor

The Standard Motor Products LSF139 is a direct-fit replacement fuel level sensor (also known as a fuel sending unit) designed to restore accurate fuel gauge readings to your vehicle's instrument cluster. This OE-quality component replaces the original sensor when it becomes worn, corroded, or damaged — eliminating erratic gauge behavior, a stuck empty reading, or a fuel gauge that no longer responds correctly.

Key Features:

• Direct OE Replacement — engineered to match original equipment fit, form, and function for a hassle-free installation
• High-Quality Construction — built to withstand the harsh environment inside the fuel tank, including exposure to fuel, vapor, and temperature extremes
• Accurate Fuel Level Monitoring — restores proper resistance signal to the fuel gauge, eliminating inaccurate or erratic readings
• Includes Gasket Where Applicable — simplifies installation with all necessary sealing hardware included
• No Remanufactured Components — manufactured new to Standard Motor Products' quality specifications
