3.37. Replacement of the fuel filter

Replacement of the fuel filter (each 170 000 km of a run)

Removal of a protection plastic cover from the lower part of the fuel filter

Gasoline is extremely dangerous and flying liquid therefore it is never necessary to neglect security measures during the work with fuel system.

On some early models equipped with system of injection of LH-Jetronic fuel, the fuel filter is located in a motive compartment between the battery and a false partition. On late models with systems of injection of LH-Jetronic or Trionic fuel the filter is in the neighbourhood with the fuel tank under the car bottom.

Dump pressure in fuel system according to the recommendations made in the Section System of Injection of Fuel - precautionary measures and dropping pressure.

Early models with system of injection of LH-Jetronic fuel

 PERFORMANCE ORDER

1. Clear areas around inlet and final unions of the fuel filter.
2. Establish under the filter the small drain capacity or dry rags for collecting the spilled fuel.
3. Unscrew a hollow bolt from a reverse side of the filter, holding the coupling an additional wrench. Remove consolidations.
4. Unscrew a hollow bolt on the forward surface of the filter, having made at the same time the same procedure.
5. Pay attention to the direction of the arrow applied on the filter case, give the holding clip and take the filter from a motive compartment.
6. Install in the new filter holding a clip and tighten a clip. Make sure that shooter, specifying the direction of a stream on the filter case, it is directed towards the final union conducting to the highway of injection of fuel.
7. Check a condition of sealing washers, if necessary replace them.
8. Establish a hollow bolt and hoses of the lower part of the filter together with sealing washers. Strong tighten a bolt, holding couplings an additional wrench.
9. Collect all spilled fuel by means of dry rags.

Late models with the LJ-Jetronic or Trionic systems

 PERFORMANCE ORDER

1. Prop up back wheels, then a back part of the car and establish to a poddomkratta it on axial props (address Poddomkrachivaniye's Section, towage and change of wheels).
2. Remove a plastic safety casing where it is established, then clear areas around inlet and final unions of the fuel filter.
3. Establish the drain capacity of small volume under the filter or put dry rags for collecting the spilled fuel.
4. Unscrew hollow bolts of connections on each end of the filter, holding the coupling by means of an additional wrench. Remove sealing washers.
5. Pay attention to the direction of the arrow applied on the filter case. Weaken the holding clip and take the filter from under the car.
6. Install in the new filter holding a clip, then tighten a clip. Pay attention to the direction of an arrow on the filter case. Make sure that shooter, specifying the direction of a stream on the filter case, it is directed towards the final union conducting in a motive compartment.
7. Check a condition of sealing washers, if necessary replace them.
8. Establish hollow bolts and hoses on each end of the filter, together with sealing washers. Strong tighten bolts, holding couplings an additional wrench.
9. Collect the spilled fuel, establish into place a plastic cover where it is available, then lower the car on the earth.

All models

Start the engine and examine all fuel hoses regarding detection of leaks.
The old filter has to be utilized safely, meaning that it is extremely flammable.
