How to drain gasoline from a car tank: all available methods

Good day to all! As you may have guessed, today we are talking to you about how to drain gasoline from a tank. But only your car, not someone else’s car.

Otherwise it will be an illegal act. So you should be careful and careful when practicing the discussed methods somewhere other than your own vehicle.

Draining fuel from a car or motorcycle tank is not a rare procedure. The only question is how best to do this in a given situation.

Precautionary measures

Draining gasoline must be carried out in compliance with certain safety measures. Mandatory rules:

• do not pump fuel near an open fire;
• do not smoke near the car, because 1 spark is enough to instantly ignite the fuel;
• You should only download gasoline on the street, because indoors you can be poisoned by its toxic fumes.

If, when downloading gasoline using a hose, fuel gets into your mouth, you must quickly rinse it with clean water. Do not suddenly pull the hose out of the tank. You just need to press the valve a little with a wooden object, and it will easily come out of the neck of the tank. After completing all the work, screw the cap on the tank tightly.

Experts recommend pouring fuel only into a canister or any metal tank. Plastic containers can create sparks and melt, so gas stations only pour fuel into steel containers.

Drain methods

The best way to pump out fuel largely depends on the vehicle and engine type.

Not all methods are suitable for modern injection engines, where there is a mesh in the gas tank.

Such a need as draining fuel can arise on any car, regardless of its status, model, or year of manufacture. It could be:

• Chevrolet Niva;
• Moskvich;
• Lada Kalina;
• Renault Logan;
• Audi A5;
• Mazda 6;
• Volkswagen Polo Sedan, etc.

That is, these can be various foreign cars or domestic cars.

As for the methods, they can be divided into the following categories:

• using a hose;
• pump;
• return;
• through the fuel line;
• using a drain plug.

Now I propose to briefly go through each of the presented methods.

Hose

If you believe the films, then using a regular hose you can drain the required amount of fuel from the fuel tank of any car without any problems. Or even everything flammable.

This is a really old and quite effective method. Its essence is extremely simple. You need to insert one end of the hose into the tank, and then begin to pull the liquid out of there with your mouth.

To minimize the risk of swallowing fuel, you should do a quick retraction and wait 2-3 seconds. In this case, the second end should be as close to the ground as possible.

Fuel should not flow immediately.

The danger with this method is that it is quite easy to drink the fuel. Even if it is a small amount, it is still potentially very dangerous to health.

You can use an alternative method and pump out the fuel using a hose with a bulb. Another interesting option will be presented in the video. Be sure to check it out at the end of the article.

Pump

If it is a foreign car, or some modern domestic car, then using a hand pump would be a more effective option.

Just check in advance whether the pump has enough power to pump out fuel. Manual models differ in volume and configuration. More expensive versions have an adapter and hose. Cheap models do not have these components; they will have to be purchased separately.

To pump out fuel you need:

• connect the hoses together;
• lower one end into the tank;
• immerse the second in a container for draining;
• start pumping;
• wait for the sound of approaching liquid;
• completely or partially empty the tank.

Depending on how much fuel is planned to be drained, it is necessary to prepare containers of the appropriate volume in advance.

Return

This method is suitable for cars with injection engines.

To use it, you must:

• turn off the engine;
• find the fuel hose located behind the fuel pump;
• for convenience, it is better to disconnect the hose in the engine compartment;
• this is the hose that goes from the tank to the ramp;
• the end of the hose is lowered into the canister to drain;
• The ignition turns on, but the engine does not start;
• the pump begins to pump liquid;
• The fuel is gradually drained through the return line into the prepared container.

Please note that some vehicles may have a fitting on the fuel rail. It is designed specifically for convenient draining of fuel. That is, just unscrew it and start the draining procedure.

If you turn on the pump and try to completely drain the gasoline, it may burn.

Therefore, to be on the safe side, it is better to start the fuel pump, let it run for a while, draining some of the liquid from the tank, then turn it off and let it rest. Then the procedure is repeated.

This method is also unpleasant because air pockets appear in the system. You can remove them by turning the engine at high speeds.

Fuel line

If we talk about some old foreign cars, as well as cars with carburetor power plants, then it is possible that the fuel pump will be located near the engine, and not directly in the fuel tank.

This situation can be used for draining. To do this you will need to find the fuel line. The procedure looks like this:

• remove the clamp from the hose from the tank to the pump;
• the tube is disconnected;
• the hose is placed in a container;
• gasoline begins to gradually drain.

The advantage is that the pump itself will not work, and therefore this method of draining does not threaten it in any way.

Drain plug

Perhaps your car has a special drain plug. You can find out about this by looking at the instruction manual.

But here a viewing hole or overpass may be required.

The procedure is extremely simple. Necessary:

• prepare the container;
• place it under the drain plug hole;
• unscrew the plug;
• remove the required amount of fuel;
• close the plug.

This completes the procedure.

When does it become necessary to drain the fuel from the tank?

Many car owners ask the question of how to drain gasoline from the tank of a Russian-made car or truck or a foreign car and in what cases such a need arises. Complete or partial draining of fuel may be necessary:

1. If the car is filled with low-quality fuel, it should be removed from the tank as quickly as possible in order to avoid failure of various components and assemblies of the vehicle.
2. If you need to refuel a generator that charges the battery.
3. If you need to give several liters of fuel to a car owner whose car has run out of gas.
4. If the gas tank is full.
5. If it's time to replace a worn fuel filter, fuel pump, flush or completely replace the tank.
6. If the car has been standing motionless for a long time and the fuel begins to separate into separate fractions.

If the car is fuel injected

Motorists who drive fuel-injected vehicles should take into account that using a hose will not completely remove the fuel. Therefore, you need to open the gas tank and perform the following steps:

1. Determine where the tube is located. It is located at the bottom of the engine and is necessary to supply gasoline to the ramp.
2. Remove the clamp and disconnect it from the pipe.
3. Turn the ignition key.
4. You need to look at another relay block. You need to understand which of them is responsible for the operation of the fuel pump.
5. It is removed, then you need to bridge it. To do this, use a paper clip.
6. Turn on the ignition. Fuel flows into the container.

After this, the hoses are returned to their places. You need to watch for leaking fuel. If bubbling appears, turn off the ignition immediately, then the pump will not be damaged.

Design

Regardless of the brand of vehicle, each gas tank has a neck into which fuel is poured and which is closed with a screw cap with a rubber seal. Some cars have a special lock on the tank cap.

The neck is located at the rear of the car on its left or right side and is connected to the gas tank via a fuel line. It is a dense rubber hose that has different diameters depending on the brand of vehicle. New vehicles may be equipped with gasoline pumps that supply fuel to the vehicle's engine. The fuel level in such cars is controlled by electronic sensors that transmit readings to the instrument panel. Electrical wires located in such pumps do not cause a car explosion.

A special ventilation system installed in the car maintains the required level of pressure. The tank can also be equipped with a gravity shut-off valve, which will prevent fuel from spilling and igniting when the machine overturns.

Methods

Important! It is necessary to work with fuel during draining only in open areas. This is necessary in order not to inhale gasoline vapors, which are toxic, which in turn is very harmful to human health.

Most often, drivers are interested in how to properly drain gasoline through a hose, since this method is the most common. A simplified version of the method involves the use of a hose or tube of the required length. So, one end must be lowered into the gas tank, which is done through the filler neck. And the second end is taken into the mouth, tightly clasped with the lips, then air is drawn in and this end is immediately lowered into a container for draining. It should be noted that the end of the pipe should not be at the same level as the tank, but lower.

Fuel pump

If the driver is faced with the task of “how to drain fuel from the tank,” then he needs to use the presented method. With fuel everything is much more serious than with oil. No syringe will be useful here. The best solution is the right fuel pump. There are several types:

• Pumps driven by an electric motor powered by a cigarette lighter or battery (connected to a clamp). Such electric pumps usually cost from 800 rubles and above.

Hand pumps. These are quite rare devices and this is not surprising. • They are usually shaped like a rubber bulb, so pumping fuel takes a long time and requires iron muscles. A pear costs about 400 rubles, so for the equivalent of two you can buy the cheapest electric pump.

• The third type of device is very interesting. It requires little financial outlay, as it costs from 2,500 rubles and above, although high-quality metal models reach 4,000 rubles. We are talking about a “mud pump”. A small device that is attached to a drill, and it sucks out the liquid to the desired level. The pump is very versatile because it can be used at home, for example, to drain water from an aquarium, pump out water from a clogged sink, etc. Its only drawback is that the pump requires a drill. When choosing a suitable device, first of all, you need to check whether the kit includes long enough tubes.

Before you start pumping, you need to see whether there is a mesh in the tank or not. Each option has its own instructions for pumping out fuel.

Nuances of the procedure

As soon as the driver begins to drain gasoline, he is often faced with incomprehensible situations. If in theory everything is quite simple, then in practice there can be difficulties. For example, the most commonplace method of pumping out gasoline is pumping it out using a “pear.” But, unfortunately, many modern cars have a curved neck or are equipped with a valve.

There is also a special mesh filter in the neck. It is not recommended to deform it. Some drivers try to break through it, but it is difficult to do. In this situation, you should find the coarse filter under the bottom of the machine. Sometimes the valve is hidden.

As for injection engines, the situation is different. Draining the fuel is quite difficult because the fuel pump is electric. Draining will require special skills and tools.

Advice from experienced motorists

The difference between new foreign cars, such as Scania, is the thin and winding fuel line. This means that you won’t be able to pull the air out of the hose using your own lungs or using a blower. A homemade piston won't help either. In this case, you will have to spend money on a fuel transfer pump that pumps up high pressure. There is no need to worry about the money spent, as with this device the operation becomes much easier and safer.

It is important to remember that some cunning drivers manage to drive up to trucks during a traffic jam and pump out fuel without permission. Such a person not only commits illegal actions, but also creates a dangerous situation on the road. Therefore, after replacing diesel fuel, it is advisable to ensure that unauthorized persons cannot gain access to the tank lid.

Features of the VAZ-2114

This model already belongs to more modern vehicles, in which the design features of the filler neck simply do not allow the use of the time-tested method described above. It is not possible to insert even a thin tube removed from the IV into it. In this regard, it will be necessary to use other, somewhat less effective methods that make it possible to remove fuel, if not completely, then almost to the very bottom.

• dismantling the tank;
• using a fuel pump;
• directly through the hole located in the cabin.

In a VAZ-2114 injector, it is unfortunately impossible to do this using a return line - this method is only suitable for older cars.

Greed, arrogance and gasoline.

Dedicated to the impudence of the gas station workers and the greed (no) of the owners of runaway carts.

Being the proud owner of an old car, I have the misfortune of constantly having to fill it up at domestic gas stations. Several times, at different gas stations, I noticed one unpleasant feature for me: when filling up to a full tank of gasoline, the meter showed more than the performance characteristics of my car. Those. with 5-7 liters of gasoline remaining, 50 liters could enter the tank when the tank capacity is exactly 52 liters. He endured it a couple of times, but on the third time he started cursing. The manager listened to me, ordered his nuker to take a measuring container and we went to check the pump. I don’t remember how much, but as much as needed was poured in. Well, I think to hell with you, goldfish. To stop being a sponsor of rosy-cheeked managers of all sorts of Lukoils, I made myself a troublesome, but very precise rule - I have been pouring gasoline into a 20-liter canister for almost a year. I pay for 20 liters exactly and go ahead. Six (!) times we filled 17-18 liters. I immediately went to the manager and showed him the receipt and the canister. Only twice did they check on the cameras that I had not poured gasoline anywhere. In other cases, they apologized and offered either money for a couple of liters (the manager simply took out a hundred and handed it over with an apology), or they added it to the tank. Maybe it will be useful to someone.

Suction unit

If a driver accidentally puts too much oil into the engine, all he will need is a suitable syringe known as a suction gun. You can buy the simplest and cheapest device for only 400 rubles. It is a large syringe with a tube that makes it easy to pump out excess oil. It is quite difficult to suck up all the oil; it is not designed for this. In addition, professional devices are much more expensive and effective, costing from several thousand rubles and are highly effective. It must be remembered that such a syringe works in both directions, and you can successfully use it as an oiler by replacing the hose with a rigid tube.

What devices can be used

Tools to help make your work easier:

• Ordinary hose.
• A syringe from a pharmacy. It can create an initial vacuum in the hose.
• Pump "pear", also known as "membrane". Helps “start” pumping out gasoline.
• Household pumps. Low-power battery-powered devices from the “shop on the couch”
• Windshield washer pump from VAZ 2101 (07, 08, 21), GAZ 2410 (3302) Daewoo Lanos, Sens (or any other with similar parameters), mounted on a hose and powered by a 12V battery

The last option shows the greatest efficiency (device performance 10 ml per second).

Why is this necessary?

To begin with, it is worth identifying a list of reasons when there is a need to find out how to drain gasoline from the tank.

Motorists mainly justify this with the following reasons:

There are more than enough reasons. The only question is why the drain will be needed in your case.

I would like to note that bad gasoline often causes engine detonation and other malfunctions.

If you observe a situation where the engine starts and stalls literally immediately, it is possible that the reason lies precisely in the quality of the filled fuel.
