Introduction

The 3806040-Q851A Fuel Level Sensor is a professional OEM-level electronic sensing part specially designed for FAW series heavy-duty trucks, including FAW New Dawei, J5P and J6 models. Installed inside the fuel tank, it accurately detects real-time fuel level height and converts physical liquid level data into standard electrical signals, ensuring precise fuel level display on the dashboard. Manufactured strictly according to original factory specifications, this sensor features standard installation size, sealing structure and circuit parameters, supporting direct plug-and-play replacement without modification. It effectively solves common faults such as inaccurate fuel display, floating fuel level value, no signal output, sensor failure and water ingress damage, providing stable and reliable fuel monitoring for heavy-duty trucks. It is a high-quality replacement part for truck repair, fleet maintenance and bulk spare parts wholesale.

Key Features

✅️Exact OEM Fit 3806040-Q851A

Standard dedicated part number perfectly compatible with FAW New Dawei, J5P, J6 heavy truck fuel tank systems. 100% matches original mounting hole size, plug interface, signal parameters and installation height, no error code or signal mismatch after installation.

✅️High Precision Fuel Level Detection

Adopts high-sensitivity resistance sensing structure with stable signal output. It accurately identifies subtle changes of fuel level, effectively avoids floating display, sudden jump data and false fuel level alarm, ensuring consistent and accurate dashboard fuel reading.

✅️Excellent Sealing & Anti-Leakage Performance

Comes with high-quality rubber sealing gasket and integrated waterproof structure. It effectively prevents fuel leakage, rainwater and dust intrusion, avoids internal circuit oxidation and short circuit, greatly improving the safety of the fuel tank system.

✅️Fuel Corrosion Resistant Material

The probe and floating ball adopt high-grade oil-resistant and anti-corrosion materials, which can resist long-term immersion of diesel and chemical erosion. Not easy to rust, deform or fail, adapting to long-term vehicle fuel storage and driving vibration.

✅️Strong Vibration & Shock Resistance

Optimized overall structural reinforcement design, stable internal circuit and fixed floating ball structure. It can resist frequent vibration and bumpy road impact during truck driving, no stuck floating ball or signal interruption.

✅️Plug & Play Easy Installation

Completely consistent with original vehicle assembly standards, with reserved standard wiring plug and fixing holes. No wiring modification or program calibration is required, saving maintenance time and labor costs.

✅️Strict Factory Testing & Long Lifespan

All sensors undergo strict signal detection, sealing test, corrosion resistance test and aging test before delivery. Stable performance, low failure rate and strong durability, suitable for long-term operation of fleet trucks.
