Removing Fuel Tank From Sea-Doo: Step-By-Step Guide

how to remove fuel tank from seadoo

If you want to remove the fuel tank from your Sea-Doo, you'll first need to drain the gas. This can be done by locating and disconnecting the fuel line from either the gas tank or the engine, then attaching a siphon or hand pump to the end of it. You can then pump the gas out of the tank and into a safe container. It's important to do this in a well-ventilated area away from any potential sparks or flames. Once the tank is empty, you can remove it without having to pull the engine. However, you will need to remove the steering and clean the fuel system, including the fuel lines, carbs, and pop-off valve.

Draining the fuel from a Sea-Doo

Locate the Fuel Line: The fuel line runs from the gas tank to the engine. Find this line so you know where to disconnect it.

Disconnect the Fuel Line: Gently disconnect the fuel line from either the gas tank or the engine. Be careful not to damage the fuel line or any surrounding parts.

Attach a Siphon or Pump: Once the fuel line is disconnected, attach a siphon hose or a hand pump to the end of the fuel line. A siphon hose can be created by cutting a 10-15 foot fuel-rated hose at an angle and placing it into the tank.

Pump or Siphon the Fuel: Start pumping or siphoning the gas out of the tank and into a safe container. Ensure you are in a well-ventilated area away from any potential sparks or flames. Keep an eye on the gas flow. When it starts to slow down or stop, the tank is almost empty.

Alternatively, if you have an air compressor, you can use a garden hose with a small hole cut into it. Insert the nozzle of your air blow gun and run it until the fuel siphons out.

It is important to note that some Sea-Doo models may have specific variations in the fuel system. Always refer to your owner's manual or seek advice from authorized Sea-Doo mechanics for detailed instructions specific to your model.

Disconnecting the fuel line

Locate the Fuel Line: Before disconnecting the fuel line, it is important to first identify its location. The fuel line typically runs from the gas tank to the engine. Make sure you have a clear understanding of the fuel line's path to avoid any confusion during the disconnection process.

Prepare the Work Area: Safety should always be a top priority when working with fuel. Ensure that you are in a well-ventilated area, away from any potential sparks or open flames. Have a suitable container ready to catch any fuel that may spill during the disconnection process. It is also recommended to wear protective gear, such as gloves and eye protection, to safeguard against any fuel exposure.

Disconnect the Fuel Line: Start by gently disconnecting the fuel line from either the gas tank or the engine. Be cautious not to damage the fuel line or any surrounding components during this process. Take your time and work carefully to avoid any leaks or accidental spills. If you are using a tool to assist in the disconnection, ensure it is suitable for the job and will not cause any damage.

Secure the Fuel Line: Once the fuel line is disconnected, securely clamp or plug the open end to prevent any fuel leakage. You don't want fuel spilling out and creating a hazardous situation. If there is a significant amount of fuel remaining in the tank, you may consider attaching a siphon or hand pump to the fuel line to safely remove it. This will allow you to transfer the fuel to a safe container for disposal or storage.

Handle Fuel with Care: Always remember to handle fuel with caution. Do not inhale fumes, and avoid any exposure to heat or open flames. Fuel can be dangerous if not handled properly, so take the necessary precautions to ensure a safe work environment.

Clean the Fuel System: With the fuel tank removed, it is a good opportunity to clean the fuel system, including the fuel lines, fuel pump, and any other components that may be accessible. Refer to specific cleaning guidelines for your Sea-Doo model to ensure a thorough and safe cleaning process.

By following these steps, you can successfully and safely disconnect the fuel line when removing the fuel tank from your Sea-Doo. Remember to work cautiously and always put safety first when dealing with fuel.

Using a siphon or hand pump

To remove the fuel from your Sea-Doo, you will need a siphon or hand pump, a spare gas container, and a hose. Some Sea-Doo models have anti-siphoning devices installed to prevent fuel theft, so check for this first. If you are unable to insert a siphon, this may be the reason.

First, locate the fuel line, which runs from the gas tank to the engine. Disconnect the fuel line from either the gas tank or the engine, being careful not to damage the fuel line or any surrounding parts. Once the fuel line is disconnected, attach a siphon or hand pump to the end of it. Place the gas can under the jet ski and insert the siphon hose into the fuel tank, with the other end of the hose in your gas can.

To start the siphoning process, take the hand pump and slowly pump the handle three or four times. Once the gas starts to flow, gravity will assist you, and the remaining fuel will be pulled from the jet ski into the gas canister. This final step should take no more than 5-10 minutes.

It is important to perform this task with caution and in a well-ventilated area, away from any potential sparks or flames. Always handle fuel with care and do not inhale fumes or expose them to heat or flame.

Cleaning the fuel tank

To clean the fuel tank of your Sea-Doo, you will first need to drain the tank. This will make it lighter to move and tilt. You can then use a pressure washer and a cleaning agent like Simple Green or Purple Power to clean the tank. Make sure the tank is completely dry before reinstalling it.

If you are unable to remove the tank, you can try cleaning it without taking it out. One way to do this is to use a vacuum or a pump to suck out any debris or sludge from the bottom of the tank, where it tends to collect. You can also try tilting the ski at an angle so that the debris settles in one corner, then use tubing to suck it out.

Another option is to use a fuel additive to clean the tank. Sea Foam Marine Pro, Ski-Doo OEM fuel stabilizer, and K100 are all recommended products for this purpose. You can also add a gallon of water and some emulsifier to the fuel to keep it in good shape.

If your Sea-Doo has disposable fuel filters, you should replace them regularly, as they can get clogged with sand, sludge, or other contaminants. Serviceable fuel filters can be cleaned, but they may not catch smaller particles. You can also install a water separator, such as the Seasense 50052103, to help trap contaminants.

Finally, you may want to clean the fuel injectors. This can be done manually by removing the injector rail and spraying it with a throttle body cleaner. You can also use an injector cleaning fuel additive or a product like STP Fuel Injector Cleaner.

Removing the engine

Next, you will need to remove the filler hose at the tank, as this will give you enough room to access the engine. You will also need to remove the steering to get out the fuel baffle. It is important to note that you don't have to pull the engine to remove the tank, but you will need to clean the entire fuel system, including the fuel lines, carbs, and pop-off valve. Soak and blow carb cleaner through all the passages and rebuild them with Mikuni carb kits.

Before putting everything back together, tune the carbs by following the directions for idle, low-speed jet setting, and high-speed setting adjustments. Once the engine is removed, be sure to clean and dry the fuel tank thoroughly before reinstalling it. You can use a pressure washer and a cleaner like Simple Green or Purple Power. Ensure the tank is completely dry before reinstalling it.
