If you need to drain the fuel tank of your Renault Scenic, it's important to note that there is no drain plug. The best method to drain the tank is to lift the rear seats to access the pump, remove the pipe leading to the engine, and supply the pump with 12V to pump out the fuel. Alternatively, you can remove the pump and siphon the fuel directly, but this can be a messy process. Another option is to jack up the car and locate the two pipes with joints behind the sifts. By squeezing the locking tabs in the joints together and pulling them apart, the fuel will flow out due to gravity. This method is suggested as it is a sealed unit with no drain plug in the tank.

What You'll Learn

There is no drain plug on the Renault Scenic
If you need to drain the fuel tank, you will have to remove it and have it professionally flushed. This is the only sure means of cleaning the tank in modern cars.
One way to drain the fuel is to jack the car up and look behind the sifts. You will see two pipes with joints. Squeeze the two locking tabs in the joints together and pull them apart, and the fuel will flow out by gravity.
Alternatively, you can try to siphon the fuel. Lift the rear seats to access the pump in the tank, take off the pipe leading to the engine, and supply the pump with 12v to pump the fuel out. If this doesn't work, you can take out the pump and siphon the fuel directly, but this will be messy.

Jack up the car and squeeze the locking tabs in the joints to drain fuel
To drain the fuel tank of a Renault Scenic, you will need to jack up the car and locate the two pipes with joints behind the sifts. Squeeze the locking tabs in the joints together and pull the pipes apart to allow the fuel to flow out by gravity.
Jacking up the car is necessary to access the fuel tank and pipes safely. Once the car is securely jacked up, locate the two pipes with joints behind the sifts. These pipes are connected to the fuel tank, and by squeezing the locking tabs in the joints, you can separate the pipes and drain the fuel.
The locking tabs are small, usually red or green buttons located in the joints of the pipes. They may be challenging to access, so having an extra pair of hands to help squeeze the tabs while you separate the pipes can be beneficial. It is also essential to have a container ready to collect the draining fuel.
Before attempting to drain the fuel, ensure that you have taken the necessary safety precautions. Wear protective gear, such as gloves and eye protection, and have a fire extinguisher nearby in case of any accidents. It is also crucial to ensure that the area is well-ventilated to prevent the buildup of fumes.
By following these steps, you can effectively drain the fuel tank of a Renault Scenic by squeezing the locking tabs in the joints of the fuel pipes. Remember to work carefully and safely throughout the process.

Remove the tank to drain it
To drain the fuel tank of a Renault Scenic, you will need to remove the tank. This is because the fuel tank is completely sealed and does not have a drain plug.
First, jack up the car and locate the two pipes with joints behind the subframe at the front of the car. Squeeze the two locking tabs in the joints together and pull them apart. The fuel will then flow out by gravity.
Alternatively, you can try lifting the rear seats to access the pump in the tank. Take off the pipe leading to the engine and supply the pump with 12v to pump out the fuel. If this doesn't work, you can try removing the pump and siphoning the fuel directly. However, this method can be messy.
Another option is to siphon the fuel through the filler or from the outlet pipe. You may need to disconnect the outlet pipe and turn on the ignition to run the pump. Keep in mind that this method may only work for a small amount of fuel.
It is important to exercise caution when handling fuel and ensure that you have the necessary knowledge, skills, and equipment to perform the task safely.

Siphon the fuel through the filler or outlet pipe
To siphon the fuel from your Renault Scenic, you will need a siphon pump and a gas can or another closed container to collect the fuel. It is important to note that siphoning fuel can be dangerous if not done properly, and it is generally not recommended if your car has an anti-siphon mechanism. Newer vehicles often have a block at the base of the fuel filler neck to prevent a hose from being inserted.
If your Renault Scenic does not have an anti-siphon mechanism, or if you are able to bypass it in an emergency, here is how you can siphon the fuel through the filler or outlet pipe:
First, locate the filler or outlet pipe. Place the hose of the siphon pump into the pipe, ensuring that the hose is pointing down into the fuel tank. Insert the other end of the hose into the gas can. If you are using an automatic pump, the fuel should now flow out of the tank and into the can. With a manual pump, you will need to pump several times to get the fuel flowing.
To avoid spilling fuel, ensure that the receiving container is placed lower than the inlet of the hose in the tank. You may need to pump a few times to get the fuel flowing, but once it is flowing freely, gravity will do the rest of the work.
When you want to stop siphoning, cover the hose with your thumb, raise it above the level of the fuel in the tank, and remove your thumb. Any remaining fuel in the hose should flow back into the tank. Remove the hose and close the tank to prevent contamination.

Disconnect the outlet pipe and turn on the ignition
To drain the fuel from your Renault, you will need to siphon the fuel from the outlet pipe. First, locate the outlet pipe. This is the pipe that connects the fuel tank to the engine. Once you have located the outlet pipe, you will need to disconnect it.
There are a few ways to disconnect the outlet pipe. One way is to use a tool to squeeze the two locking tabs in the joints together and then pull them apart. This will allow you to separate the pipe and the fuel will begin to flow out. Be careful, as the fuel will flow out quickly and it is dangerous. If you are unable to find the locking tabs, you may need to remove the bolts that hold the pipe in place.
With the outlet pipe disconnected, you can now turn on the ignition. This will activate the fuel pump, which will start to draw fuel from the tank. The fuel will flow out of the disconnected outlet pipe. You may need to bridge the relay or provide a direct power supply to the pump to keep it running.
It is important to note that working with fuel can be dangerous, and it is recommended that you wear protective gear and take appropriate safety precautions. It is always best to consult a professional mechanic or a specialist if you are unsure about any part of this process.
