The Honda EU3000is generator is a powerful tool with a reputation for reliability. However, as with any machine, maintenance is required to keep it running smoothly. One common issue that owners face is a rusty fuel tank, which can cause serious problems if not addressed. This is often due to fuel being left in the tank for extended periods, leading to degradation and potential blockages. To resolve this, the fuel tank must be accessed and sometimes even removed or replaced, which can be a complex process. This involves disassembling significant parts of the generator, including the exterior shrouding, handles, panels, and various bolts. Proper precautions must be taken to ensure safety when handling fuel.

What You'll Learn
Removing the fuel tank without disassembling the generator
To remove the fuel tank from a Honda EU3000is generator without disassembling the generator, you will need to follow a few steps. Firstly, it is important to prioritise safety when working with gasoline. Ensure you work in a well-ventilated area away from any ignition sources. Wear safety glasses and fuel-resistant gloves for protection.
Now, let's move on to the steps for removing the fuel tank:
- Prepare the generator by placing it on a flat, level surface outdoors or in a well-ventilated area.
- Turn off the engine and allow it to cool down completely for at least 15 minutes.
- Disconnect the spark plug wire to prevent accidental starting.
- Turn the fuel valve to the "OFF" position and remove the fuel tank cap to relieve any pressure in the tank.
- Place an approved gas container below the carburetor drain to catch any fuel that may drain out.
- Locate the carburetor drain screw by opening the left side maintenance cover using a flathead screwdriver to release the latch.
- Remove the front fascia and any fasteners where the top cover is attached to the fuel storage.
- Access the fuel tank and clean it with an appropriate solution or replace it if necessary.
- To reinstall the fuel tank, follow these steps in reverse and ensure all connections are secure.
It is important to note that proper maintenance and fuel handling can help prevent fuel-related issues. Regularly check fuel lines and connections for any leaks or damage, and clean the fuel sediment cup every 100 hours or 6 months. Additionally, always store your generator with the fuel valve turned off to prevent leaks.

Cleaning the tank without removing it
To clean the fuel tank of your Honda EU3000is generator without removing it, you can try the following methods:
Firstly, it is important to inspect the fuel tank for any signs of rust or sludge. If there is rust, you can try using EvapoRust, a product that removes rust without damaging the tank. Drain the gasoline from the tank, close the fuel valve, and use EvapoRust, leaving it to soak for around 24 hours. Then, drain the tank and flush it out with clean, stabilized gas.
Alternatively, if there is sludge, you could try an engine degreaser, leaving it to sit before rinsing thoroughly. You could also try adding a solvent to the tank and sloshing it around to dislodge debris.
If you are able to access the inside of the tank, you could try using compressed air to blow through and clear any blockages. You could also try to remove the fuel filter to gain better access to the inside of the tank. This can be done by removing the air cleaner housing and the fuel shut-off knob, then loosening the nut holding the valve to the bottom of the tank.
If you are unable to clean the tank effectively without removing it, you may need to take the generator apart to access the tank. This involves removing the front and back panels, handles, side panels, and muffler assembly. Remember to take pictures as you go so you can reference them when putting everything back together.

Draining the fuel tank
To begin draining the fuel tank, first prepare your generator: Move the generator to a flat, level surface outdoors or in a well-ventilated area. Turn off the engine and allow it to cool completely for at least 15 minutes. Disconnect the spark plug wire to prevent accidental starting. Turn the fuel valve to the OFF position. Remove the fuel tank cap to relieve any pressure in the tank. Place an approved gas container below the carburetor drain to catch the fuel. Never attempt to drain fuel from a hot engine, as this can be extremely dangerous. Working on a cool engine in a well-ventilated area reduces fire and fume hazards.
The carburetor drain screw is the key to emptying the fuel system on your Honda EU3000is. To locate it: Open the left side maintenance cover using a flathead screwdriver to release the latch.
These final steps help protect the fuel tank from corrosion during storage. Leaving a thin coating of fresh fuel prevents rust from forming inside the metal tank. Always store your generator with the fuel valve off to prevent any possibility of leaks.

Removing the main cover
To remove the main cover of your Honda EU3000is generator, you will first need to remove the front and back black panels, as well as the front and back handles. Next, remove the left and right side panels. You will then need to remove the back muffler assembly and the muffler heat shield.
Now you can access the four bolts that hold the tank to the upper frame rails. Remove these bolts, as well as the petcock on the bottom of the tank. Finally, remove the two top rails, and you should be able to slide the tank out.
You will mostly need a 10mm wrench and a 10mm socket to remove the bolts. It is recommended to take pictures as you work so that you can more easily put everything back together.
Note that this process is specific to the Honda EU3000is generator and may not apply to other models.

Reinstalling a new tank
To reinstall a new tank in your Honda EU3000is generator, you will need to reverse the steps you took to remove the old tank.
Firstly, place the new tank into the generator, sliding it into position. Ensure that you have kept the four rubber grommets from the old tank and pressed them into the new one, as the new tank does not come with them. Secure the tank to the upper frame rails using the four bolts.
Next, reattach the two top rails that you removed to slide out the old tank. Then, reattach the back muffler assembly and the muffler heat shield. Now, you can start to reassemble the exterior of the generator by reattaching the left and right side panels, followed by the front and back handles, and finally the front and back black panels.
It is recommended that you take pictures during the removal process so that you can refer to them when putting everything back together.
Finally, before using your generator, ensure that you have properly drained and cleaned the old tank or installed a new one. This is important to prevent fuel-related issues and to keep your generator running smoothly. Always use fresh, high-quality unleaded gasoline (87 octane or higher) and consider adding a fuel stabilizer if the gas will sit for more than 30 days. Keep the tank full to prevent condensation during storage, and run the generator at least once a month for 30 minutes to maintain optimal performance.
