How to clean the fuel tank?

service rarely contains a procedure such as cleaning the fuel tank. It is usually operated until the vehicle operates. But it is important to remember that elimination of consequences is more costly and expensive measures.

Why is it important to clean the tank?

clogged tank can lead to:

  • Failure to work the engine;
  • complicated engine starting after prolonged downtime;
  • Formation of clogging in filters and fuel nozzles;
  • Losing tightness due to severe rust damage.

water

This is the most common type of contamination. Water is very dangerous for the car. It enters the fuel system through a diluted fuel. Water can also condense from the air in the tank. Due to more weight, compared to the fuel, it settles to the bottom. It then spreads through the fuel system. This fluid is especially dangerous in winter - because of its low temperature it freezes and creates an obstacle. Water also activates corrosion processes.

how to clean fuel tank There are several ways. The first option is to use methyl, ethyl or isopropylov. The product used should be clean, do not contain impurities. The tank of 50 liters requires about 0.5 liters of alcohol. If the motor is diesel, then the alcohol is replaced by machine oil. Alcohol is combined with water, forming a burning mixture.

tank system.

The second option is more costly - you need to drain all the fuel and completely dry the tank.The easiest way is to do this on cars with a drain hole. Otherwise, the fuel ramp will be required.

Another way is chemical solutions called moisture. You can buy them in auto shopping. Road -habitats eliminate moisture and help combat corrosion. It is important to choose proven syllables.

other contamination

precipitation, dirt get into the tank mainly from low quality fuel. They settle to the bottom and gradually disrupt the fuel system.

How to wash the fuel tank of diesel and gasoline in this case? Washing will require cleaning or soap solution. If there is a drain hole, the tank is not required. But it is better to remove it - it will increase the quality of cleaning.

soap solution or cleaning agent is poured through the neck, after which you need to carefully roll the tank. Alternatively, water under pressure is allowed. After draining the water, the procedure is repeated. They do it until it is clean. Then pour some fuel into the tank and drain. Now it is necessary to dry the tank and it is ready for further operation.

rust

rust appears due to additives in fuel, muddy sediment, water. It is also facilitated by the use of aggressive moisture.

how to clean the fuel tank from rust:

  1. Using a strong water pressure. It can be used to remove large flakes and a slight coating. It is possible to enhance the effect by adding small nuts or fractions to the tank.
  2. Using special reagents. Usually, orthophosphoric acid, acetone or other corrosion converters are used to combat rust.
  3. Electrolysis method. It is resorted to in advanced cases. The procedure is dangerous, so it is better to trust its specialists.

Baka cleaning with special converters is carried out in personal protective equipment and in a ventilated room.The tank is removed, after which it is poured into hot water or kerosene, gasoline (with severe contamination). The tank should be shaken strongly and drain the liquid. The process is repeated several times.

In the next step, the tank is dried with a hairdryer and a chemical reagent is poured into it. It is diluted in water according to the instructions. The tank is shaken again and left for a while, periodically repeating the procedure.

How to wash the fuel tank from the reagent? First, it is poured into the soda solution (100 grams per 10 liters of water). After that it is necessary to rinse the soda residue with water and to carry out quality drying. Now the tank can be installed in place.

preventive measures

To prevent the formation of serious contamination, it is recommended to clean the fuel container with a certain frequency. To protect the tank helps treatment of walls with epoxy resin, the use of anti -corrosion additives. You should also refue on the tested gas stations. It is not recommended to pour the fuel into the tank in wet weather. If you do not do without it, then you need to top up.

Hopefully the recommendations how to wash the fuel tank of the car will be useful.
