Setup and Installation
The Jiawu Fuel Tank Level Indicator is designed for simple installation using a standard 5-hole mounting pattern. Ensure the vehicle's fuel tank is empty or at a very low level before beginning installation to prevent fuel spills and ensure safety.
Safety Precautions:
- Always disconnect the vehicle's battery before working on fuel system components.
- Work in a well-ventilated area, away from open flames or sparks.
- Wear appropriate personal protective equipment (PPE), such as gloves and eye protection.
- Ensure the fuel tank is depressurized before opening.
Installation Steps:
- Prepare the Mounting Area: Locate the existing fuel tank access port or the designated area for the fuel level indicator. Ensure the surface is clean and free of debris.
- Remove Old Unit (if applicable): If replacing an existing unit, carefully remove it, ensuring no fuel spills.
- Position the Gasket: Place the provided gasket onto the mounting surface of the fuel tank. This gasket ensures a tight, sealed fit.
- Insert the Indicator: Carefully insert the Jiawu Fuel Tank Level Indicator into the tank opening, aligning the 5 mounting holes on the indicator with those on the tank.
- Secure with Screws: Use the six provided screws to firmly attach the indicator to the fuel tank. Tighten the screws evenly to ensure a proper seal and prevent leaks. Do not overtighten.
- Connect Wiring (if applicable): While this is a mechanical indicator, some installations may require connecting to an existing gauge or warning light. Refer to your vehicle's specific wiring diagram if electrical connections are necessary. Ensure all connections are secure and insulated.
- Test for Leaks: After installation, add a small amount of fuel to the tank and visually inspect for any leaks around the newly installed indicator. Address any leaks immediately.

Operating Instructions
The Jiawu Fuel Tank Level Indicator provides a direct, mechanical reading of your fuel level. The gauge displays the fuel level using a needle that points to markings from 'E' (Empty) to 'F' (Full), with intermediate markings for 1/4, 1/2, and 3/4.
Reading the Gauge:
- The needle will move in response to the fuel level in the tank.
- When the needle points to 'E', the tank is empty or near empty.
- When the needle points to 'F', the tank is full.
- Intermediate markings (1/4, 1/2, 3/4) indicate corresponding fuel levels.
The gauge offers a display accuracy of 5%, allowing for reliable monitoring of your fuel supply. Regularly check the gauge to plan refueling stops and avoid running out of fuel.

Maintenance
The Jiawu Fuel Tank Level Indicator is designed for durability and minimal maintenance. Its sealed design helps protect internal components from contaminants.
General Maintenance Tips:
- Regular Inspection: Periodically inspect the visible parts of the indicator for any signs of damage, cracks, or loose connections.
- Cleaning: Clean the exterior of the gauge with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the plastic or markings.
- Check for Leaks: Occasionally check the mounting area for any signs of fuel leakage. If a leak is detected, re-tighten the mounting screws (do not overtighten) or replace the gasket if necessary.
- Environmental Protection: While the unit is designed for high-temperature tolerance, prolonged exposure to extreme conditions outside the specified range (-40°C to 85°C) may affect its lifespan.
