4. Unscrew bolts of fastening and uncover with consolidation. Address to an accompanying illustration.

Removal of the right sensor of a fuel tank with the fuel pump

 PERFORMANCE ORDER

1. Unscrew bolts of fastening and uncover (1). Address to an accompanying illustration.

2. Rasstykuyte tips (1) and (2). For this purpose open clamps. Address to an accompanying illustration.
7 Mark fuel hoses (3) and (4) sticky tape and disconnect them from the sensor of a fuel tank, having opened collars.

The fuel system is under pressure. Therefore a hose remove carefully. The flowed-out fuel wipe a rag.

8 Carefully unscrew in blows a cap nut (5). Repair trucks apply for this purpose the BMW 16 1 020 tool. It can be made also by means of wooden whetstone. Formation of sparks is not allowed thus.

3. Lift the sensor, incline it aside and take out. Thus enclose a rag and wipe the flowed-out oil.

4. Compress the holder of the fuel pump (the black case). Take out the pump from a pot (the white case). Address to an accompanying illustration.

5. Disconnect from the fuel pump both of the tip (1). Address to an accompanying illustration.
6. Open collars (2). Open a collar of a spiral hose. Carefully disconnect a hose from the fuel pump.

Collars of a cable are located at height of white markings. Pay attention to it at installation.

4. Carefully unscrew in blows a cap nut (5). Repair trucks apply for this purpose the BMW 16 1 020 tool. It can be made also by means of wooden whetstone. Formation of sparks is not allowed thus.

5. Lift the sensor. From the bottom party compress two clamps of a pipe of the pump and remove a pipe. Take out the sensor of a fuel tank. Thus enclose a rag and wipe the flowed-out oil.

Installation

Sealing rings of the sensor of fuel surely replace with the new.


 PERFORMANCE ORDER

1. Left sensor of a tank:
18 Insert the sensor and hold it approximately in 5 cm over a tank. Insert a pipe into the pump.
Right sensor of a tank:
19 Fix the fuel pump at the sensor of fuel and attach hoses.

2. For an exception of distortions before installation of the sensor of a tank expose a spiral hose and a cable (2) between the sensor of level (1) and the fuel pump (3). Address to an accompanying illustration.

3. Expose the tank sensor. Thus the pad at the top part of the sensor of fuel should enter into a groove at a tank. The sensor should settle down vertically in a tank. Dnishcheva measuring щуп should be in a groove of the bottom of a tank.
4. Fix a cap nut the moment of 35 Nanometers. Thus the rotary lock should be fixed distinctly in the corresponding sample on a tank.
5. Put on fuel hoses according to the put markings and fix them new collars.
6. Join tips and fix them.
7. Establish a cover and fix it. Pay attention to the correct provision of consolidation.
