8.1.3. Fuel level sensor

GENERAL INFORMATION

PETROL ENGINE

In each compartment of a fuel tank there is a sensor of indication of level of fuel.

Removal



PERFORMANCE ORDER
1. Merge fuel from a tank. If only one sensor is dismantled, it is necessary to merge fuel only from this compartment.
2. Remove drain топливопровод (74) with a standard clip (011).
3. Remove drain топливопровод on a basic plate of the fuel level sensor (B4/1). For this purpose weaken and shift back a shlangovy clip.
Prevention

The flowed-out fuel collect rags or merge in suitable capacity. Connecting input of the pipeline close a suitable stopper, or insert into a hose a pure bolt with suitable diameter of a carving.


4. Unscrew a round nut (89/1). In a repair truck the special tsapfovy key is for this purpose applied. If you have no such key, insert into shlitsa of a safety ring a suitable plastic wedge and weaken a ring in easy blows of a hammer.
Prevention

Do not apply some metal because of danger of emergence of a spark.


5. Take the fuel level sensor.
6. Remove pipelines (88/3) and (88/4) from the jet soaking-up pump on the fuel level sensor.

Installation

PERFORMANCE ORDER
1. Get pipelines (88/3) and (88/4) on the fuel level sensor.
2. Establish the fuel level sensor, having equipped it with new profilirovanny consolidation so that thorns of the sensor entered into gearing in grooves (88/2) fuel tanks.
3. Twirl a tsapfovy key a round nut with the moment of 55 N of m.
4. Get a drain hose and fix it a shlangovy collar, remove a shlangovy clip.
5. Fill in fuel and at the working engine check tightness of all points of connection.

DIESEL ENGINE

In each compartment of a fuel tank there is one fuel level sensor.

Removal

PERFORMANCE ORDER
1. Merge fuel from a tank. If the sensor only acts in film, it is necessary to release its clips only.
2. Disconnect a standard clip (011) drain fuel lines (70).
3. Remove the drain line from a locking plate of the fuel level sensor. For this purpose weaken and shift back shlangovy clips.
Prevention

Collect rags the following remains of fuel or catch them in a suitable vessel. A flange of the pipeline close a stopper, for example, a pure bolt with suitable diameter of a carving which insert into the pipeline.


4. Turn off a nut (89). In a repair truck the special tsapfovy wrench is for this purpose applied. If there is no such key, put in a groove of a safety ring a suitable plastic wedge and weaken a ring in easy blows of a hammer.
Prevention

Do not use metal: danger of an iskreniye!


5. Take the fuel level sensor.
6. Remove pipelines (90) from the ezhektorny pump on the fuel level sensor.

Installation

PERFORMANCE ORDER
1. Get the pipeline (90) on the fuel level sensor.
2. The fuel level sensor with a new profile sealing ring (89/1) establish so that pins of the sensor entered into gearing in grooves of a fuel tank.
3. Screw an eye nut a tsapfovy wrench with the moment of 55 N of m.
4. Put on a drain fuel hose and fix it a clip for a hose. Remove from a hose the plug.
5. Fill in fuel and check tightness of all junctions at the working engine.
