Removing the fuel tank
To remove the fuel tank from your 2003 Suzuki GSXR 600, you will need to follow a few steps to ensure a safe and effective process. Here is a detailed guide to help you with the task:
Firstly, locate the fuel tank and prepare the necessary tools for the removal process. Place the motorcycle on a stable surface and engage the parking brake to ensure it doesn't move during the procedure. Wear protective gear, such as gloves and eye protection, to safeguard against any fuel spills or debris.
Next, carefully remove the fuel tank by loosening and detaching any hoses, lines, or connections attached to it. This may include fuel lines, vents, and electrical connections. It is important to label or take note of the orientation of these connections to facilitate proper reinstallation. Once all the connections have been safely detached, slowly lift the fuel tank away from the motorcycle frame. Be cautious, as the tank may be heavy and still contain some fuel residue.
After removing the fuel tank, place it on a clean, flat surface. You may want to cover the surrounding area with a drop cloth or old newspaper to catch any fuel spills or debris during the cleaning process. At this point, you can also inspect the tank for any signs of damage, rust, or corrosion.
Now, you can begin the cleaning process. Using a suitable fuel tank cleaner, such as kerosene or a specialised fuel tank cleaning product, thoroughly clean the interior and exterior of the tank. Ensure that you follow the instructions on the cleaning product carefully and allow adequate ventilation during the cleaning process. Pay close attention to areas that may be prone to debris buildup or rust, such as the fuel pump assembly and the bottom of the tank.
Finally, once the tank is clean and dry, you can prepare it for reinstallation. Inspect all the hoses, lines, and connections that you previously detached and replace any worn-out or damaged parts. Refer to your service manual or seek advice from a Suzuki GSXR forum if you need guidance on specific connection points or procedures. Before reinstalling the fuel tank, ensure that all necessary maintenance tasks related to the fuel system have been completed, such as cleaning or replacing fuel filters and injectors.
By following these steps, you can effectively remove, clean, and prepare your 2003 Suzuki GSXR 600's fuel tank for reinstallation, ensuring optimal performance and fuel system health. Remember to consult manufacturer guidelines, service manuals, or seek advice from experienced mechanics or GSXR enthusiasts if you have any questions or concerns during the process.

Cleaning the injector screens
Removing the Injector Screens
Before you begin cleaning, you'll need to remove the injector screens from your Suzuki GSXR 600. Here are the steps to safely remove them:
- Remove the fuel tank: Start by taking off the fuel tank to access the fuel pump. It might be a little stuck, but it will pop out.
- Access the fuel pump: With the tank removed, you'll see the fuel pump. Remove the nuts and screws holding the wires to the base of the pump.
- Separate the pump assembly: Hold the top of the pump and carefully separate it from the base. There is a rubber O-ring inside that makes this step a bit tricky, so be patient and gentle.
- Remove the filter: Using a flat-head screwdriver, carefully work the filter off the plastic piece. Be very gentle during this step, as it is easy to tear the filter's plastic housing.
Now that you have removed the injector screens, it's time to clean them:
- Spray with cleaner: Spray the injector screens with a suitable cleaner. You can use carb cleaner or a product specifically designed for cleaning fuel injectors.
- Reinstall the injector screens: After cleaning, reinstall the injector screens by following the removal steps in reverse. Ensure that the filter is seated properly and securely attached.
Additional Maintenance Tips
While cleaning the injector screens, you can also perform some additional maintenance to ensure your fuel system is in optimal condition:
- Backflush the pump: It is recommended to backflush the pump assembly to remove any built-up residue. You can use compressed air, but be cautious and avoid using too much pressure.
- Clean the fuel tank: Consider cleaning your fuel tank with a suitable product, such as Kreem A & B or kerosene. This will help remove any contaminants that could clog your fuel filter or injectors.
- Check for leaks: After reassembling the fuel pump, check for any leaks, especially around the O-rings. Replace the O-rings if necessary to avoid fuel leaks.
By following these steps, you can effectively clean the injector screens on your 2003 Suzuki GSXR 600 and maintain the performance and health of your motorcycle's fuel system. Remember always to refer to a qualified mechanic or a detailed service manual if you have any doubts about the process.

Back flushing the pump
Step 1: Prepare the Work Area
Park the motorcycle on a level surface and place a drain pan or container underneath the fuel pump to catch any spilled fuel. Remove the fuel tank and set it aside, ensuring that the area is well-ventilated to prevent the buildup of fumes.
Step 2: Disconnect the Fuel Lines
Locate the fuel lines connected to the pump and carefully disconnect them. You may need to label or mark the lines to ensure proper reconnection during reassembly. Place a rag or towel over the disconnected lines to prevent dirt or debris from entering the fuel system.
Step 3: Remove the Fuel Pump
Loosen and remove the nuts and screws holding the fuel pump in place, being mindful that the pump may be stuck to the tank. Gently slide the pump out and set it aside, taking note of any electrical connections or wires attached to it.
Step 4: Disassemble the Fuel Pump
Hold the top of the pump and carefully separate it from the base. There may be a rubber O-ring or gasket that creates a tight seal, so use a flat-head screwdriver to carefully pry the two parts apart without damaging the components.
Step 5: Clean the Fuel Pump Components
Using a suitable cleaning solution, such as carb cleaner or a fuel system cleaner, spray the internal components of the fuel pump, including the screen and filter. Allow the cleaner to soak for a few minutes to help loosen any built-up dirt or debris.
Step 6: Back Flushing the Pump
Using a clear hose connected to a water source or another pump, insert the hose into the hole where the fuel pump normally sits. Ensure that the outlet of the hose is immersed in the cleaning solution or water. Cover the pressure relief valve to prevent air from being sucked in, and turn on the water source or pump. Flush water or cleaning solution through the pump in the opposite direction of normal fuel flow to dislodge and remove any accumulated debris.
Step 7: Reassemble the Fuel Pump
After back flushing, carefully reassemble the fuel pump by sliding the pump back into its housing and securing it with the appropriate screws and nuts. Ensure that all electrical connections are properly reconnected and that the fuel lines are securely attached.
Step 8: Final Checks
Before starting the motorcycle, inspect the fuel pump and lines for any signs of leaks. Check the fuel filter for any remaining debris or buildup. If necessary, repeat the back-flushing process until the filter is clean.

Using a flat-head screwdriver
To clean the fuel filter on a 2003 Suzuki GSXR 600, you will need to remove the fuel tank and pull out the fuel pump. Here is a step-by-step guide using a flat-head screwdriver:
First, remove the fuel tank and locate the fuel pump. The pump might be stuck to the tank, but it will come out with a gentle pull. Now, remove the three nuts holding the wires to the base of the pump, and then remove the screw from each side of the fuel pump using your flat-head screwdriver.
Next, hold the top of the pump and separate it from the base. There is a rubber O-ring inside that makes it a little tough to come off, so be sure to apply some force when pulling it apart. Once separated, you will be able to see the filter inside. Using your flat-head screwdriver, carefully work the filter off the plastic piece it is attached to. Be gentle, as you do not want to damage the plastic housing.
Now that the filter is removed, you can clean it. Spray the screen with a cleaner of your choice, and use a straw to spray inside the filter as well. Ensure that you clean it thoroughly. Before putting the filter back in, make sure it is completely dry. Reattach the filter to the plastic piece, ensuring it is seated all the way. Now, you can put the fuel pump back together, making sure the O-ring is seated correctly.
Finally, while you have the tank off, it is a good idea to clean it as well. You can use Kreem A & B or an equivalent product, such as kerosene.
