Disconnecting the fuel line
Locating the Fuel Line:
Before disconnecting the fuel line, it is important to correctly identify it. The fuel line typically runs from the gas tank to the engine. If you are having difficulty locating it or accessing it, it may be due to the specific design of your Sea-Doo model or a possible anti-siphoning device installed to prevent fuel theft.
- Once you have located the fuel line, gently disconnect it from either the gas tank or the engine. It is important to perform this step gently to avoid damaging the fuel line or any surrounding parts.
- After disconnecting the fuel line, you can attach a siphon or hand pump to the end of it. This will enable you to pump the old fuel out of the tank and into a safe container.
- Ensure that you perform the pumping process in a well-ventilated area, away from any potential sparks or open flames. Always handle fuel with caution and avoid inhaling fumes or exposing them to heat or flame.
- During the pumping process, maintain visual contact with the gas flow. When the flow starts to slow down or stop, it indicates that the tank is almost empty.
- After successfully draining the gas, properly reconnect the fuel line to prevent any leaks.
Tools for Disconnecting:
To disconnect the fuel line, you may require specific tools depending on the type of connectors used in your Sea-Doo GTX. Quick-disconnect fittings, for example, require a tool that fits around the small hose and slides into the larger fitting to release the clip. These tools are readily available at auto parts stores or online. Metal disconnect tools are generally recommended over cheaper plastic ones for their durability and effectiveness.
By following these steps and taking the necessary precautions, you can safely and effectively disconnect the fuel line of your Sea-Doo GTX, allowing you to purge old fuel from the tank.

Using a siphon or hand pump
To purge old fuel from the tank of a Sea-Doo GTX using a siphon or hand pump, follow these steps:
Firstly, 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. You may need to remove the battery and the compartment above the fuel tank to access the fuel line.
Once the fuel line is disconnected, attach a siphon or hand pump to the end of it. You can use a cheap manual hand pump or siphon pump, such as a $6 hand pump from Harbor Freight. Alternatively, you can use a clear vinyl line or a garden hose, which you can suck on to start the siphon.
Before you begin pumping, ensure you are in a well-ventilated area away from any potential sparks or flames. Then, start pumping the gas out of the tank and into a safe container. Keep an eye on the gas flow as you pump. When the flow starts to slow down or stop, it indicates that the tank is almost empty.
Finally, remember to properly reconnect the fuel line once you have drained the gas.
Note that some Sea-Doo models may have anti-siphoning devices installed, so if you are unable to insert a siphon, you may need to take your Sea-Doo to a professional mechanic.
