Key benefits include:
- Removes growth, varnish, and gel from ethanol.
- Minimizes sludge and other fuel contaminants.
- Helps extend the life of new fuel sending units.
- Low-suds cleaning solution for easy treatment and rinsing.
- Suitable for fuel tanks up to 40 gallons capacity.
2. Safety Information

- Skin and Eye Contact: In case of skin contact, wash thoroughly with soap and water. For eye contact, flush with water for several minutes and consult a physician if irritation persists.
- Flammability: While the cleaning solution itself may not be highly flammable, fuel tanks contain residual fuel. Ensure no open flames, sparks, or ignition sources are present during the cleaning process.

4. Setup
- Prepare Work Area: Ensure you are working in a well-ventilated area, preferably outdoors or in a garage with open doors.
- Gather Tools: You will need basic tools to safely remove the fuel tank from your vehicle, containers for draining old fuel, and a water source for rinsing.
- Drain Fuel Tank: Safely drain all remaining fuel from the tank into an approved container. Dispose of old fuel according to local regulations.
- Remove Fuel Tank: Carefully remove the fuel tank from the vehicle following your vehicle's service manual instructions.
- Inspect Tank: Visually inspect the inside of the tank for the type and extent of contamination (e.g., rust, sludge, varnish, debris).
5. Operating Instructions
Follow these steps for effective cleaning of your fuel tank:
- Wear Protective Gear: Put on the provided gloves and any other necessary personal protective equipment (e.g., safety glasses).
- Add Cleaning Solution: Pour the entire bottle of Delphi FC01 cleaning solution into the empty fuel tank.
- Add Water: For tanks up to 40 gallons, add water to the tank until it is approximately half full. For smaller tanks, adjust the water volume proportionally to ensure adequate dilution and coverage.
- Agitate Solution: Seal the tank openings securely. Gently rock or rotate the fuel tank to agitate the cleaning solution and ensure it comes into contact with all internal surfaces. Continue agitation for 15-30 minutes, or longer for heavily contaminated tanks.
- Soak (Optional): For stubborn deposits, allow the solution to soak in the tank for several hours or overnight. Periodically agitate the tank during this period.
- Drain Solution: Carefully drain the used cleaning solution from the tank into an appropriate waste container.
- Rinse Tank: Thoroughly rinse the inside of the fuel tank multiple times with clean water until all traces of the cleaning solution and loosened contaminants are removed. Use the lint-free cloth to wipe down accessible internal surfaces if necessary.
- Dry Tank: Allow the fuel tank to air dry completely before reinstallation. Ensure no moisture remains inside, as this can lead to rust or fuel system issues.
- Reinstall Tank: Reinstall the clean, dry fuel tank and new fuel pump/sending unit according to your vehicle's service manual.
6. Maintenance
The Delphi FC01 Fuel Tank Cleaning Kit is a single-use product for cleaning. To maintain a clean fuel system and prevent future contamination:
- Use Quality Fuel: Always use high-quality fuel from reputable sources.
- Regular Fuel Filter Replacement: Replace your vehicle's fuel filter at recommended service intervals.
- Avoid Low Fuel Levels: Try to avoid consistently running your vehicle on very low fuel levels, as this can draw sediment from the bottom of the tank.
- Periodic Inspection: If possible, periodically inspect your fuel tank for signs of contamination, especially if using ethanol-blended fuels which can contribute to varnish and water accumulation.
7. Troubleshooting
If you encounter issues during or after the cleaning process, consider the following:
- Incomplete Cleaning: If significant deposits remain after the first cleaning cycle, repeat the operating instructions. For extremely heavy contamination, multiple cycles or professional tank cleaning may be required.
- Persistent Odor: Ensure the tank is thoroughly rinsed and completely dry. A lingering odor may indicate residual cleaning solution or fuel vapors. Allow for extended drying time in a well-ventilated area.
- Difficulty Draining: If the tank has internal baffles or complex shapes, ensure all drain plugs are accessible and open. Tilting the tank may help.
- Fuel System Issues After Reassembly: If your vehicle experiences fuel delivery problems after reassembly, double-check all connections, ensure the new fuel pump/sending unit is correctly installed, and verify that the fuel filter is clean and properly fitted.
