Take the hose that comes with your fuel siphon system and insert one end into the fuel tank. Make sure the hose is securely in place to avoid any leaks.

Start pumping:

Turn on your manual or electric pump and begin pumping the fuel out of the tank. The fuel will be drawn out through the hose and into your fuel container.

Monitor the process:

Keep an eye on the fuel flow to ensure that the container is filling at a steady pace. Adjust the tubing if necessary to avoid air bubbles, which can impede the flow.

Stop the flow when nearing the desired amount:

When you are close to reaching the desired amount of fuel to drain, you can stop the flow by raising the end of the tubing or the container to a level higher than the fuel in the tank. This will cause the flow to reverse, and any residual gas in the pump will drain back into the tank.

Remove the hose and secure the fuel tank:

Once you have drained the desired amount of fuel, remove the hose from the tank carefully. Close the fuel tank securely to prevent any leaks.

Clean and store your equipment:

After you have finished draining the fuel, clean your siphon pump according to the provided instructions. Usually, this involves pumping a mixture of soap and water through the device and letting it air dry. Store your fuel siphon system and other tools in a safe place.

Dispose of the drained fuel properly:

It is essential to dispose of the drained fuel correctly. Do not pour it down a drain or onto the ground. Take the old fuel to a certified disposal facility or recycling centre, or contact your local environmental waste disposal centre for guidance on hazardous waste collection.
