Removal and installation of the sensor of a stock of fuel / fuel pump

At the BMW car of the 3rd series the sensor of a stock of fuel is located in each chamber of a fuel tank. For check of sensors they are necessary for removing. In the sensor of the right chamber, at a look in the movement direction, there is a fuel pump. Therefore for removal of the pump it is necessary to remove the right sensor.

- Do not use near a workplace open fire, do not smoke and do not hold any strongly warmed up subjects. There is a danger of accident! Keep in readiness the fire extinguisher.
- Watch normal ventilation of a workplace. Fuel pairs are poisonous.
- The fuel system is under pressure. When opening system fuel can escape under pressure. Collect fuel a rag. Use goggles.


 REMOVAL

Before removal of the fuel pump empty a fuel tank, having passed on the car. Works whenever possible should be carried out in the open air and at good ventilation. Also radial fan which electric motor is located outside of an air stream can be applied to ventilation of a workplace.

1 Disconnect a negative cable (-) the storage battery at the switched-off ignition. The battery is in a luggage compartment behind a cover on the right side. At BMW 316i, 318i cars the battery settles down in an impellent compartment.

As a result of shutdown of the storage battery data from memory of malfunctions of some monitors are erased. If necessary before shutdown of the battery it is necessary to consider these memories of malfunctions. Address to the Section Diagnostics of malfunctions. Work it is desirable to lead HUNDRED in conditions.

2 Remove a back seat, address to the Section Removal and installation of a back seat.

3 Remove a rubber epiploon-1-at the left or on the right under a seat. Cast away an insulating mat.

4 Unscrew screws of fastening and uncover-2-.

The right sensor with the fuel pump:

5 Rasstykuytes I will corrode - 1-. Thus release a clamp, having compressed it.

6 Mark a tape fuel hoses-2-and-3-and disconnect them from the stock sensor for what open collars.

The fuel system is under pressure therefore a hose remove slowly and wipe the flowed-out fuel.

7 Carefully unscrew in blows a cap nut-4-. HUNDRED are applied for this purpose by the BMW 161020 tool. It can be carried out also by means of wooden whetstone.

It is not necessary to apply the metal tool since formation of sparks is thus possible.

8 Lift up the stock sensor, take him aside and take out. Thus enclose a rag and wipe the flowed-out fuel.

Left sensor of a stock:

9 Unscrew screws of fastening and uncover-2-.

10 Rasstykuytes I will corrode - 1-sensors of a stock. Thus compress clamps.

11 Disconnect a fuel hose-2-from the stock sensor for what weaken a collar-2-.

The fuel system is under pressure therefore the hose is necessary for removing slowly. If necessary wipe the flowed-out fuel.

12 Carefully unscrew in blows a cap nut. HUNDRED are applied for this purpose by the BMW 161020 tool. It can be carried out also by means of wooden whetstone.

It is not necessary to apply the metal tool since formation of sparks is thus possible.

13 Lift the stock sensor, take him aside and take out. Press from the bottom party a clamp-1-and remove a leveling hose of a tank. Take out the sensor. Thus enclose a rag and wipe the flowed-out fuel.



 INSTALLATION

Surely replace sealing rings of sensors of a stock.

Left sensor of a stock:

14 Be convinced that the return valve-1-is inserted into a leveling hose of a tank.

15 Insert the sensor and hold it approximately on 5 cm above a tank. Fix the sensor in a groove on a tank.

16 Level the sensor, having turned it. Thus the pad in the top part of the sensor should enter into a tank groove.
17 Put on and tighten a cap nut. Thus the lock should enter a pad into the corresponding groove on a tank, having distinctly fixed.
18 Attach fuel hoses according to markings and fix them new collars.
19 Join shtekerny connections and fix them.
20 Establish a cover and fix it, watching thus the correct provision of consolidation.
21 Insert into a cover a rubber epiploon. Put back an insulating mat.
22 Establish into place a back seat, address to the Section Removal and installation of a back seat.
23 Attach a negative cable (-) the storage battery at the switched-off ignition. Establish hours.

24 Check work of the index of a stock of fuel on the dashboard.

If the fuel tank does not manage to be emptied in the course of movement, it specifies that the tank equalizer between the right and left chambers incorrectly works. In this case it is necessary to remove at first the right sensor with the fuel pump. Then to remove the left sensor and to check, whether the leveling hose-1-in a settler-2-is fixed. After check establish back both sensors.
