How to drain gasoline from a tank Method No. 1 If there is no mesh in the tank

Most often, there is no mesh in the tank in Russian-assembled cars. To drain the fuel, you should use a special tube; this is the most primitive, most common method.

What you will need: -hose; - a container into which we will drain gasoline.

First of all, you need to open the gas tank by unscrewing the cap from the filler neck. Next, one end of the hose is inserted into the tank, and the second is lowered into a container into which gasoline will later need to be drained. In order for gasoline to flow, it is necessary to create pressure, and this can be done quite simply with the help of air. You just need to inhale a little air through the tube. After this, you should lower the free end into the bowl and wait until the gasoline flows.

Draining process using a pump:

You can also use a special hand pump to drain fuel for pumping out flammable liquids such as gasoline or diesel fuel. You can buy this pump at an auto store. Please note that not all hand pumps available in stores are suitable for pumping out fuel. Therefore, before purchasing a pump, make sure that it is approved for pumping fuel liquids.

Please note that once you have drained all the fuel, do not yank the hose to remove it from the tank. Firstly, you will not be able to pull out the hose this way, and secondly, you may damage the hose.

The fact is that there is a special small valve in the fuel tank that holds the fuel in the tank and prevents fuel from splashing and getting on the tank cap. That is why, once you insert the hose into the tank, it is so difficult to pull it out. This valve holds the hose. In order to remove the hose from the fuel neck (from the tank), you need to press the valve, unlocking the hose. To do this, you need to push the valve a little inside the fuel neck, and holding it in this position, pull the rubber hose out of the tank without any problems. After pulling out the hose, release the valve and close the tank with the lid.

Attention! If you use a metal screwdriver to hold the valve in the tank, be sure to ground it before you touch the valve. The fact is that if you do not ground a metal screwdriver, then upon contact with the car a microspark can form, which can easily ignite fuel vapors in the tank. It is noteworthy that if you completely drain the fuel from the gas tank, there will be enough fuel vapor in it to cause your car to catch fire

Method No. 2 If a mesh is installed in the tank

The first method is suitable only for those cars that do not have a mesh on the gas tank. If it is available, and almost all modern Japanese cars have it, then you need to do it a little differently. This method is faster and safer than the first, since with the first option there is a high probability of inhaling gasoline vapors, which can lead to poisoning by its vapors.

-set of tools; - a canvas that can be laid on the ground; -gloves; - a container into which we will drain gasoline.

For the second option, you just need to open the cap located at the bottom of the gas tank. This is not as easy to do as it seems at first glance, because to do this you will have to get into a rather hard-to-reach place - to the bottom of the fuel tank, and only after that you need to unscrew the cap. After these manipulations, you can start draining the gasoline.

If the car is fuel injected

It is absolutely impossible to completely empty the fuel system of an injection car using a hose. Therefore, in order to drain gasoline from an injection car, you will need to take a different route. First, you should open the gas tank itself (neck), after which the algorithm of actions will be approximately as follows: - find the tube located at the bottom of the engine, supplying fuel to the ramp; - remove the clamp from it and disconnect it from the pipe; -turn the ignition key; - in the relay block, determine the one that is responsible for the fuel pump; -after removing it, you need to bridge it, for which it is convenient to use a standard paper clip; - turn on the car ignition; -drain the leaking fuel into a prepared container, then return the hoses and relays to their places. Important! Using this method of releasing the fuel system, you should carefully monitor the leaking gasoline - as soon as it “bubbles”, the ignition should be turned off immediately, which will avoid damage to the pump.

Method 2. Drain gasoline through the fuel line and the plug at the bottom of the gas tank

If the fuel pump is located not in the tank itself, but near the engine, you can try to drain the fuel through the fuel line. Procedure:

1. Unscrew the clamp and disconnect the hose going from the tank to the fuel pump.
2. Place the hose into the fuel container.

Fuel will leak from the gas tank. The main thing is that the end of the fuel line, as well as the fuel container, is located below the gasoline level.

Some cars have gas tanks with drain plugs. If you are the owner of just such a car model, you need to use an overpass or inspection hole to drain the fuel. This is done simply:

1. Place a container under the drain plug in the gas tank.
2. Unscrew the plug.
3. Drain the fuel (all or part of it).
4. Tighten the plug.

However, plugs at the bottom of the tank are not very common. In this case, the fuel pump will help drain the gasoline. The method is suitable for old modern cars.

Selecting a fine filter

The abundance of consumables on the market makes it difficult to choose. Surveys show that more than a third of “ten” owners use the BIG brand. The brands SCT, Bosch, Mann and Nevsky have proven themselves well.

“Experts” recommend assessing consumables visually by opening the casing. It is unlikely that such an “examination” makes sense. The differences are not fundamental; they are impossible to see with the naked eye. Universal advice - buy one that you don’t mind spending money on.

Removing gasoline from the car interior

This method cannot guarantee complete removal of fuel, but it is quite effective.

It turns out that you can remove gasoline directly from the VAZ

. In this case, it is necessary to take a number of security measures. The fact is that working with fuel in a small confined space can lead to big problems. If a spark occurs, ignition and fire may occur. It is impossible to exclude the occurrence of a spark. It may appear even if you have removed the terminal on the battery.

This means that the entire procedure should be done exclusively on the street:

• first you need to remove the seat located at the back;
• Now you can get to one of the fuel pump modules;
• once this is done, you will need to remove the module. Before you begin this task, you need to disconnect it from the system and strain out all the remaining fuel using a syringe or a special rubber bulb.

Advice. You can also use another pump, but then you will need to turn on the electricity.

Remember that you don’t need to use up all the gasoline before the engine stops completely, otherwise you may damage the fuel pump. It’s easy to burn this unit, but replacing the pump will cost you a decent amount.

How to turn on the fuel pump

Now all that's left to do is to start the fuel pump bypassing the ECU.

This can be done in two ways.

In the first case, we will be helped by a lonely dangling electrical connector, which raises many questions among firemen.

What is this chip under the hood near the fuse box? I have an unconnected connector sticking out, what is it? Where should I connect this connector?

Well, in general, this lonely connector became the most mysterious in the car and legends were made about it even more than about the octane corrector feature

In fact, this is a very useful thing in capable hands. This connector is connected directly to the fuel pump. And even after the fuel pump relay. It is this fact that makes our life much easier.

The bottom line is that we only need to have one piece of wire about 20 cm long to use it to connect our connector to the positive terminal of the battery and our pump will start working immediately

And it will work until we turn it off.

This is how easy it is to turn on the fuel pump.

Well, what should you do if your car doesn’t have such a miracle connector as the Lacetti?

It's OK. The task will become a little more difficult.

The first step is to remove the cover from the fuse box and look at the location of the elements on it.

You need to find the location of the fuel pump relay. The inscription will look like this - FUEL PUMP RELAY

We now find it on the fuse and relay mounting block. Here it is

Now you need to remove the relay and replace it with a jumper between pins 30 and 87. The contacts are signed on the relay itself, so no questions will arise.

Attention! As soon as you close the contacts, the fuel pump will immediately turn on! You don't need to turn on the ignition for this! Therefore, place a gasoline container under the fuel line in advance!

After draining the gasoline, remove the jumper and install the relay in place.

Attention! Do not turn on the pump when the tank is empty! It may fail!

That's the whole simple process.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

The most famous method of draining fuel using a hose with a diameter of 15 mm, which was used by our grandfathers, is quite effective, although dirty. Not everyone knows how to suck gasoline into their mouth. If you are not careful, you can easily spill gasoline or drink it accidentally.

Here's how to properly drain fuel:

• a hose 1-1.5 meters long is inserted into the fuel tank;
• then the liquid is drawn into the mouth from the opposite end of the tube, which is then quickly lowered into the container;
• After the container is completely filled, the hose is pulled out of the tank.

There is a special bulb on sale that perfectly absorbs liquid. You can use it if you don’t want to swallow gasoline.

There is another option. You need to take shoe laces and a hose of the same size. Then make a knot at the end of the laces and lower the rope into the hose. The tube is placed in the tank. As soon as you pull the cord, gasoline begins to flow through the tube. It turns out to be something like a piston like a syringe. To avoid any difficulties, it is recommended to soak the rope knot in any liquid in advance.
