Fuel filter for Kia Rio: technical regulations for replacement, removal and installation by yourself

The cleanliness and timeliness of oxygen entering the fuel equipment is extremely important to ensure the performance of the vehicle and the power unit as a whole. The completeness of combustion of the fuel mixture determines throttle response, acceleration dynamics, and power indicators. Lack of air leads to depletion of the combustible mixture, engine detonation, and reduced power.

Kia Rio cars are equipped with two fuel filters: coarse filter (mesh filter - a mesh bag) and fine filter (plastic block with a filter element inside). Both filters are components of the fuel module located in the fuel tank.

Technical regulations for replacement

In order to maintain the functionality of the technical product, the manufacturer recommends replacing the Kia Rio fuel filter every 30,000 km. mileage In this case, maintenance is carried out every 15,000 km. In practice, this interval is not maintained. Car enthusiasts who care about their vehicles update cleaning elements every 10,000 km.

The replacement process is not at all complicated; every car owner can do it. Specialists are rarely called to the workshop in case of detection of a large-scale breakdown or other malfunction that requires prompt intervention by a professional.

If you don't change, what will happen?

If you do not change the component in time, you will heavily load the pump, which will find it difficult to push fuel through the system, because the fuel pump screen is already clogged. The car will begin to pick up speed worse, its power will decrease, and the original dynamics will disappear. Sometimes you will observe power dips when the internal combustion engine is running. This is especially noticeable when driving uphill.

The engine will start worse day by day - until the moment when it fails altogether. And this happens sometimes.

Problems with the filter will increase fuel consumption. For example, if previously a car consumed 9–10 liters per 100 km, then with a clogged filter this figure can increase to 11–12 liters. Dips will appear when you press the accelerator pedal. This can lead to an accident when overtaking on a country highway when you need to accelerate sharply.

At that moment, when you are standing at a traffic light, the engine speed in idle mode can fluctuate - right up to the point where the internal combustion engine stalls. You will remain standing at the crossroads - there is little pleasure in this.

The process of replacing a part on the Rio model is presented in this video:

Reduced fuel pressure Kia Rio

In operating condition, the fuel pressure in the system is significantly higher than atmospheric pressure. To prevent uncontrolled spills of gasoline, all work related to depressurization of the system is carried out with the pressure released. To relieve pressure, first turn off the fuel pump by removing the fuel module power connector or removing the fuse. Then the engine is started and the remaining fuel is exhausted. Without additional actions, the pressure drops on its own 2–3 hours after the ignition is turned off.

To work, you will need a flathead and Phillips screwdriver. The procedure for releasing pressure is as follows.

1. Remove (if necessary, pry up with a screwdriver) the plastic cover of the fuse box located to the left of the steering column.
2. In operating condition, the fuel pressure in the system is significantly higher than atmospheric pressure.

5. To remove the fuel module (instead of removing the fuse), lift the rear seat and trim flaps underneath, unscrew the mounting screws, remove the hatch cover and disconnect the module's power connector.
6. Start the engine and wait for it to stop spontaneously.
7. Use the starter to turn the crankshaft several times.

Which filter to choose

When choosing a part, it is necessary to take into account the type of internal combustion engine. Officially, KIA Rio 3 with diesel power units was not supplied to the Russian market. There are only a few such machines in Russia. Finding an original fuel filter for such cars is very difficult. It is best to purchase an analogue from Bosch.

There is no point in buying cheap Chinese filtration systems. Their prices are lower, but the quality of the filters themselves leaves much to be desired. They purify diesel fuel worse. The risk of power plant failure increases.

It is easier to purchase a filtration system for KIA RIO 3 with a gasoline engine. The volume of the power plant does not affect the selection of parts. Engines with a volume of 1.4 and 1.6 liters use the same filtration system. Moreover, a similar unit is used on KIA Sportage, Sorento and some Hyundai cars (Accent and Elantra).

It is best to search for an original filter in stores by its article number - 31112-1R000. Analogues from AMD, Finwhale and Nipparts are also suitable. Factory part numbers for these parts are AMD.FF45, PF731 and N1330330, respectively.

Replacing the fuel filter on KIA Rio 2015, 2016 and earlier years of production is best combined with installing a new filter mesh. It is used as a preliminary filtration system and prevents massive foreign particles contained in gasoline from entering the filter. Mesh article number – 31184-1R000. As an alternative, it is better to use a mesh from the Cross company with article number KM79-01114.

How to replace the fuel filter on a Kia Rio - step-by-step instructions

In order to replace the fuel filter on Kia Rio cars, you must perform the following steps:

1. The fuel module is located in the fuel tank located under the rear passenger seat.

2. Lift the seat cushion and remove the fastening brackets from the holders.
3. Remove the rear seat cushion completely. Under the seat there is an access hatch to the fuel module. To open it, use a knife, because... it is glued with sealant (although self-tapping screws would be quite suitable for fixing it).
4. Disconnect the fuel module power supply (ignition must be turned off).

5. Using pliers, remove the fuel vapor supply hose to the adsorber. Remove the fuel supply pipe.
6. Remove the tube holder from the mount on the fuel module cover. Using a socket wrench 8, unscrew the bolts securing the fuel module cover plate.

7. Open the rear doors of the car to ventilate fuel vapors. Remove the fuel module from the fuel tank (be careful not to damage the float).
8. Now, to get to the fine and coarse filters, you have to disassemble the fuel module. First remove the fuel level sensor. To do this, disconnect the sensor connector from the module cover.

9. Remove the wires from the holders. Use a screwdriver to pry the sensor retainer and slide it down.
10. Next, disconnect the fuel pump power plug. Disconnect the tube that supplies fuel to the fine filter. To do this, use a screwdriver to pull out the lock.
11. Separate the cover and the fuel module glass. Now you should remove the fine filter with the fuel pump built into it from the glass.

12. To remove the fuel pump from the filter housing, press the clamps. Disconnect the fuel coarse filter from the fuel pump.
13. When disassembling the fine filter, disconnect the O-ring and the remaining wire. Disconnect the pressure regulator and the remaining fuel drain pipe.

14. The fuel filter has been removed. That's it, now you should assemble the fuel module with new filters in reverse order.

Car enthusiasts recommend carrying out preventive maintenance followed by replacement every 10,000 km. In this case, you can count on the longevity of the technical device. Premature replacement of the cleaning element is also justified in the case of systematic filling of the tank by 40 - 60%. The likelihood of sediment formation increases several times.

Signs of filter failure

The only way a filter can break is by getting clogged. The blockage prevents the normal passage of gasoline. Symptoms of blockage are:

• the car refuses to start (or starts with difficulty);
• the engine runs jerkily;
• the car accelerates worse than before;
• unstable operation at idle;
• noise during pump operation;
• decrease in pressure in the fuel line (norm - 345 kPa).

If any of the above are observed, the problem is most likely a clogged filter. It's worth replacing.

The filter becomes clogged gradually, making it difficult for the car owner to determine the initial stage of contamination, but at the final stage the engine simply will not start.

How to select a new component?

Authorized Kia dealers recommend using only original filters. If you are the owner of a Rio 3, then the OE number of the main filter element is 311121R000.

The element looks like this:

In addition to original spare parts, you can use analogues from well-known manufacturers.

Typically, car owners believe that a fine filter should be under the hood. But this is not the case with Rio 3. The part is located in the fuel tank (as well as coarse cleaning). On the fuel pump in the tank there is also a mesh (original number - 31090-1G000), which is a coarse filter. If you wish, you can change it too.

Mobis spare parts for Kia and Hyundai cars are better suited than others. This company is a supplier to the assembly line of this automaker.

Replacing the KIA Rio fuel pump mesh

After removing the KIA Rio fuel pump, it is necessary to visually inspect its grid, after which the grid should be cleaned or replaced.

The process of replacing the KIA Rio fuel pump mesh:

• By disconnecting the connector and bending a couple of latches, you need to remove the fuel level sensor
• Next, you need to separate the outer and inner parts of the KIA Rio fuel pump by releasing the fastening latches (there are three of them)
• It is not at all necessary to disconnect the corrugated tube.
• The mesh is very difficult to remove, so to remove it you will need to apply force or even pry it off with a flat screwdriver, removing the “swing”
• Clean the bottom of the glass and replace the mesh

After the KIA Rio fuel pump is installed and all the wires are connected to it, you will need to check all connections for leaks with an assistant. This is done as follows: the driver must turn the ignition key, but not start the car, and his assistant must check for leaks at the connection points. If no problems are found during the inspection, then you can tighten the KIA Rio fuel pump cap and replace the sofa. It is also important to note that starting the engine with an empty fuel pump is not recommended.

Thus, replacing the KIA Rio fuel pump mesh or the entire structure is a fairly simple procedure, but at the same time very useful and effective. The quality and serviceability of the KIA Rio fuel pump directly depend on the quality of the fuel poured into it.
