8.1.3. Fuel level sensor

PETROL ENGINE
In each compartment of the 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, then it is necessary to merge fuel only from this compartment.
2. Remove a drain fuel-supply line (74) with a standard clip (011).
3. Remove a drain fuel-supply line on a basic plate of the fuel level sensor (B4/1). For this purpose weaken and shift a hose clip back.
Prevention

Collect the flowed-out fuel by rags or merge in suitable capacity. Close connecting input of the pipeline a suitable stopper, or insert into a hose a pure bolt with a suitable diameter of a carving.
4. Unscrew a round nut (89/1). In auto repair shop the special tsapfovy key is for this purpose applied. If you have no such key, insert a suitable plastic wedge in vents of a safety ring and weaken a ring easy blows of the hammer.
Prevention

Do not apply 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. Install the fuel level sensor, having equipped it with the new pro-thinned-out consolidation so that thorns of the sensor entered gearing in grooves (88/2) of the fuel tank.
3. Put a tsapfovy key the round clamp with of 55 N.' moment of m.
4. Spread a drain hose and record it a hose collar, remove a hose clip.
5. Fill in fuel and at the working engine check tightness of all points of connection.

DIESEL ENGINE

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

Removal

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

Collect by rags the following remains of fuel or catch them in a suitable vessel. Close a flange of the pipeline a stopper, for example, a pure bolt with a suitable diameter of a carving which insert into the pipeline.
4. Turn off a nut (89). In auto repair shop the special tsapfovy wrench is for this purpose applied. If there is no such key, then put a suitable plastic wedge in a groove of a safety ring and weaken a ring easy blows of the hammer.
Prevention

Do not use metal: danger of sparking!

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

Installation

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