Once properly installed, the FOLIAGE GM46A fuel tank functions as the primary reservoir for your vehicle's gasoline. Ensure that only the appropriate fuel type (gasoline) is used, as specified by your vehicle manufacturer. Regular filling and monitoring of fuel levels are part of standard vehicle operation.

6. Maintenance

The FOLIAGE GM46A fuel tank is designed for durability and minimal maintenance. However, periodic inspection is recommended to ensure continued safe operation.

• Visual Inspection: Periodically inspect the exterior of the fuel tank for signs of corrosion, dents, or physical damage.
• Leak Detection: Check all fuel lines, connections, and the fuel sending unit seal for any signs of fuel leaks. Address any leaks immediately.
• Strap/Mounting Check: Ensure that the tank straps or mounting bolts remain secure and free from corrosion.
• Cleaning: Keep the exterior of the tank clean from dirt and debris, especially around connections and seals.

7. Troubleshooting

If you encounter issues after installation, consider the following common troubleshooting steps:

• Fuel Leaks: Re-check all fuel line connections, hose clamps, and the fuel sending unit gasket. Ensure all components are properly tightened and sealed. If a leak persists from the tank body, the tank may be defective and require replacement.
• Improper Fit: If the tank does not fit correctly, double-check the vehicle's year, make, and model compatibility. Verify that all mounting points align with the vehicle's chassis. Refer to the product dimensions and images provided to confirm the correct part.
• Fuel Gauge Malfunction: This is typically related to the fuel sending unit, its wiring, or the gauge itself, not the tank. Ensure the sending unit is correctly installed and wired.
