Mercedes-Benz W140 S-Class Fuel Level Sender — Modernized Tube-Type Reproduction (Replaces OEM 1405420104)

Upgrade your Mercedes-Benz W140 with this newly engineered fuel level sender designed for 1992–1996 models and built as a direct replacement for OEM part 1405420104.

This improved sender assembly is produced using premium-grade components, including PTFE-insulated wiring, Viton seals, and a precisely injection-molded top section that matches factory dimensions for a perfect fit.

Instead of the original string-style level sensor — often known for giving inconsistent readings — this upgraded version uses a high-accuracy tube-type sensor calibrated to mirror OEM ohm values for dependable fuel level measurement.

Each unit has been extensively tested in real-world driving, including validation on a 1993 Mercedes W140 S500, ensuring long-term reliability before release.
