Draining The Honda Eu2000i Fuel Tank: Step-By-Step Guide

how to drain fuel tank from honda eu2000i

The Honda EU2000i is a portable generator that can be drained of fuel for storage. This is a recommended practice, especially for long-term storage, as gasoline can go bad within a month or two. There are a few methods to drain the fuel tank, including using a super siphon to transfer the gas to a separate container or burning it by running the engine.

Remove gas from the Honda EU2000i before storing it

To prepare your Honda EU2000i for storage, it is best to remove all the gas from the generator. If you are unable to do this, you can treat the fuel with a stabilizer like Sta-bil. This is good practice for short-term storage as gas can go bad very quickly—even within one or two months.

First, change the oil. After you've done this, drain the gas by siphoning it into a gas can. You can use a super siphon for this. Run the engine to burn up any last bits of fuel. At this point, the tank will be empty, but there will still be gas in the carburetor.

The Honda EU2000i has a carb drain screw under the bowl, which you can use to drain the carburetor. You can reach the drain screw through the access panel on the side opposite the key switch. There is a vinyl hose from the drain screw outlet to a port on the bottom of the case.

Use a fuel stabilizer like Sta-bil if you can't drain the tank

If you can't drain the tank of your Honda EU2000i, you can use a fuel stabilizer like Sta-Bil to keep the fuel fresh. Sta-Bil is designed to prevent fuel from going stale due to evaporation and stop it from degrading further. It is important to note that Sta-Bil is a preventative product and cannot revive old or deteriorated fuel.

Sta-Bil can be used in all gasoline engines, including vehicles, motorcycles, generators, and boats. It is safe for both fuel-injected and carbureted engines and will not damage catalytic converters or oxygen sensors. The product works effectively in all gasoline blends, including ethanol-blended fuel.

When using Sta-Bil, it is important to follow the recommended dosage. One ounce (30 milliliters) of Sta-Bil treats up to 2.5 gallons (9.5 liters) of fuel. It should be used with fresh fuel, and the tank should be kept 95% full to avoid condensation build-up during storage.

To use Sta-Bil, simply add it to the fuel tank and run the engine for 5 minutes. This ensures that the entire fuel system is treated, not just the fuel stored in the tank. For seasonal storage or when the fuel is likely to sit idle for more than 1-2 months, Sta-Bil can keep the fuel fresh for up to 24 months.

By using Sta-Bil, you can prolong the life of the fuel and ensure quick and easy starts for your Honda EU2000i, even after extended storage periods.

Change the oil before storing the generator

To change the oil on a Honda EU2000i generator, you should first refer to your owner's manual for the oil change schedule, the recommended oil type, and any specific tools needed. Before starting, ensure your generator is turned off, all receptacles are unplugged, and the spark plug is disconnected to prevent accidental start-up. Run the generator for a few minutes to warm the oil, which will make it easier to drain, then shut it off and let the engine cool.

Use a flathead screwdriver to remove the maintenance cover and set it aside. The Honda EU2000i generator does not have an oil drain plug, so you will need to drain the oil from the oil fill tube. Place a drain pan next to the generator, underneath the oil fill tube. Tilt the generator towards the drain pan and allow the oil to drain fully. When empty, tilt the generator back and wipe up any excess oil with a rag.

Insert a funnel into the fill tube and refill the engine with the recommended oil type, usually Honda 10W-30. Bring the oil level to the upper limit of the oil fill tube neck. When the oil begins to run out, the level is correct. Screw the oil dipstick back into the oil fill tube and wipe up any excess oil.

Start the engine and check for any oil leaks. It is important to check the oil level before and after each use to ensure the correct amount for your engine to run properly. Regular oil changes will help prolong the life of your generator and keep it running smoothly.

Siphon the gas into a gas can

To siphon the gas from your Honda EU2000i generator into a gas can, you will need to purchase a siphoning tool, such as a super siphon. First, you should change the oil if it has been run for about 40 hours since its last oil change. Once the oil has been changed, place a gas can below the generator and use your siphon to drain the gas from the tank. Run the engine to burn any remaining fuel. Although the tank will now be empty, there is still gas left in the carburetor.

If you are unable to remove the fuel from the engine, you can treat it with a fuel stabilizer like Sta-bil. This is good practice for short-term storage as gas can go bad very quickly—even within one or two months. If you are preparing your generator for long-term storage, it is best to remove all the gas.

Run the engine to burn remaining fuel

Running the engine to burn the remaining fuel in your Honda EU2000i generator is a good way to ensure that the carburetor is not left full of fuel. This can be done by first opening the side cover and unplugging the kill switch, then starting the generator to run it out of fuel. Once the generator has died, put the choke on and start it up again. It will run for a few seconds until it runs out of fuel.

Alternatively, you can use a product called SEF, which is designed to be added to the machine after use and run for a minute or two to prevent fuel-related issues.

Another option is to use a siphon to drain most of the fuel, then start the generator and run it out of gas, which should only take a few minutes. You can then drain the remaining fuel from the carburetor bowl through the drain plug and tubing.

If you want to be absolutely sure that all the fuel is drained, you can open the drain nut and crank over the engine a few times. This will drive any remaining gas through the pump and out of the carburetor.

It is important to note that some people are uncomfortable with leaving the kill switch unplugged, as it requires cutting or tapping into the kill switch wires.
