Automotive fuel pumps are of two types: electrical and mechanical. The former push the gasoline into the engine, while the latter pull the fuel out of the tank. Both options are equipped with a mesh filter, which can become dirty over time. Due to pollution, the load on the fuel pump increases, which can even cause its complete failure.
In order to flush the fuel pump you need:
1. Gasoline pump
4. Filter mesh
5. Screwdriver
6. Wrench
I present to your attention detailed instructions: how to flush the fuel pump with your own hands
After the car has traveled about 100 thousand km, as well as with its frequent use with almost empty tank(experts recommend operating it half-filled), diagnose the car's fuel pump. If the pressure that the fuel pump creates in fuel system insufficient, it may affect engine power. Sometimes it may even happen that due to interruptions in the operation of the fuel pump, the engine may suddenly stop starting, in which case it is first necessary to check the filtration system. Often, these breakdowns are associated with contamination of the inlet grid of the fuel pump, over time, the holes in it become clogged due to the content of all kinds of dust particles, rust and sand in the fuel.
2. Try to determine by ear the serviceability or malfunction of the fuel pump. The main criterion is its much noisier operation. This is possible in cases where the filter mesh is not able to pass required amount fuel due to the fact that contamination or defects prevent this. In such cases, the electric motor of the fuel pump works, as they say, for wear and tear, with huge overloads, which as a result leads to its premature exit out of service.
3. Check and visually inspect the fuel pump strainer. To do this, you need to de-energize it in any way convenient for you: by removing the relay or by turning off the fuse. Then start the engine to reduce the pressure in the fuel system. After a few seconds, the engine will shut down.
4. After that, you need to remove the cover of the hatch access to the pump. Then clean it from dirt and dust that is on its surface. Disable main pipelines using a screwdriver and wrench, or simply pry the tabs out of the connectors. Now you can remove the fuel pump.
5. In the case of a simple fuel pump design, the filter mesh will be located outside. Remove it and rinse under running water, then make sure that all clogs and small particles are removed. Sometimes they are quite tiny, such that they are practically invisible to the naked eye. After washing, dry the filter thoroughly.
6. If the model of your fuel pump provides for the presence of a bulb, you will have to carefully disassemble it. Then you should turn off all fuel level sensors. Next, remove top cover, and remove the fuel pump from the flask. The procedure is the same - cleaning, rinsing with a jet of water, drying or installing a new filter.
To find out what condition the fuel system is in, you need to check its performance. To do this, you must connect to the gasoline supply system measuring device. In order to connect a pressure gauge to the fuel system, you must use special device. Therefore, in this case will have to go to a specialized workshop. For self check, can be used like this:
- We turn on the ignition. If fuel pump did not work or publishes extraneous noise the petrol delivery unit may be overloaded.
- If the engine performance is reduced, the acceleration period has increased, or the engine does not operate correctly at Idling, the cause may be excessive clogging of the fuel lines.
As a rule, a clogged fuel filter leads to such consequences.
In this case, the filter requires mandatory replacement, and the grid can be cleaned with your own hands. In most cases, clearing the grid gives the desired result for a while. However, the price of the part is not so high, and you can replace it without resorting to the help of workshops.
The replacement process will not take much money and time, however, it will increase the life of the fuel pump and other elements of the system.
Do-it-yourself fuel pump mesh cleaning.
To carry out the work, you need to stock up on the following materials:
- Compressor.
- Fuel pump gasket.
- Fitting seal.
In order to clean the hard filter, the fuel pump must be dismantled.
- Turn off the car's power supply.
- Unscrew the holders and remove the cover.
- We remove the electric drive.
- We unfasten the fitting and the conductor through which the fuel circulates.
- We also take out the fitting and remove the fuel outlet hose.
- Remove the seal.
- Raise gasoline compressor and remove the float. Next, together with the mixture level analyzer, we dismantle the fuel pump.
- At the bottom of the pump, there is a mesh (coarse filter).
Determine mesh contamination visual inspection It's hard enough. Small particles can interfere with the proper functioning of the fuel, while remaining almost invisible. For successful washing of the mesh, it is necessary to let it soak in a special solution. For this, it is necessary to separate detergent one in ten with water. Next, you need to place the grid in the tank with the prepared composition and leave it there for one hour.
After that, you can proceed to the main stage of cleaning.
- To do this, use the same composition and a brush with a fine pile. Using the indicated materials, thoroughly rinse the mesh.
- After that, it is necessary to clean the filter with a stream of air. To do this, we use a compressor.
- Next, you need to wait until the filter is completely dry. After that, you can assemble the fuel pump.
After washing the element, it is necessary to re- visual diagnostics. The network should not have mechanical damage. Otherwise, the element can no longer be used and the filter must be replaced.
After carrying out all the stages of work, we assemble the fuel pump in the opposite order. Next, you need to check the correct operation of the fuel system and the success of the operation.
During the operation of the car, it is necessary to pay attention to malfunctions in the fuel system in a timely manner and regularly replace used filters.
Happy repair!
As you know, the engine is the most important component of the car. Main feeder element working mixture In the engine system is a fuel pump, which is responsible for supplying gasoline to the filter element and further to the place of combustion.
The period of operation of the elements of the engine system and the fuel pump, including, is not to a small extent affected by the quality fuel mixture. In frequent cases, the use of insufficiently refined gasoline leads to a malfunction vehicle. If the fuel pump is clogged, the car starts to move jerkily or does not start at all.
The first step in restoring the function of the car, in this case, is to replace the fuel pump grid.
During the operation of the machine, the fuel pump mesh is pretty clogged and its condition can surprise even an experienced motorist.
In what cases does the fuel pump grid change.
To find out what condition the fuel system is in, you need to check its performance. To do this, it is necessary to connect a measuring device to the gasoline supply system. In order to connect the pressure gauge to the fuel system, you must use a special device. Therefore, in this case, you will have to contact a specialized workshop. For self-checking, you can use the following:
- We turn on the ignition. If the fuel pump does not work or makes abnormal noise, the gasoline delivery unit may be overloaded.
- If the engine performance is reduced, the acceleration period is extended, or the engine is not idling properly, the cause may be excessive clogging of the fuel lines.
As a rule, a clogged fuel filter leads to such consequences.
In this case, the filter requires mandatory replacement, and the mesh can be cleaned with your own hands. In most cases, clearing the grid gives the desired result for a while. However, the price of the part is not so high, and you can replace it without resorting to the help of workshops.
