Mercedes W140 Fuel Level Sensor Assembly – Modernized Upgrade, OEM‑Spec Replacement 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 such as 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.
