Fuel module engine 11183 (1.6i) — cleaning the mesh filter (VAZ-2114)

Note: One of the reasons for low fuel pressure in the fuel rail may be a dirty fuel module mesh filter.

Advice: If you suspect that the pressure regulator is faulty, it must be replaced.

Removal

1. Remove the fuel module (see "Fuel module engine 11183 (1.6i) - removal and installation").

2. Remove the fuel level indicator sensor (see "Fuel module engine 11183 (1.6i) - replacement of fuel level indicator sensor").

3. Using thin-nosed pliers, remove the retaining ring from the fuel module guide cover.

Warning! Use a marker to mark the guide on which the spring is mounted. The spring must not be moved to another guide.

4. Having removed the guide covers from the fuel module housing, remove the spring.



5. Disconnect the three fasteners.





6. Remove the fuel pump assembly with the mesh filter from the housing.



7. Remove dirt deposits from the fuel module housing and wash the housing in clean gasoline.

8. Wash the mesh filter in acetone and blow it out with compressed air (from a compressor or foot pump).

Recommendation: If the mesh filter is heavily soiled and cannot be cleaned, replace it or the fuel module assembly.

Installation

We assemble the fuel module in the reverse order of disassembly.
