The right gauge with the fuel pump:

5 Rasstykujte a socket-1. Thus release a clamp, having compressed it.

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

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

7 Cautiously turn on blows накидную a nut-4. HUNDRED are applied for this purpose by tool BMW 161020. It can be carried out also by means of wooden бруска.

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

 INSTALLATION

Necessarily replace sealing rings of gauges of a stock.

The left gauge of a stock:

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

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

16 Level the gauge, having turned it. Thus the pad in the top part of the gauge should enter into a tank groove.
17 Put on and tighten накидную a nut. Thus the lock should enter a pad into a corresponding groove on a tank, distinctly having fixed.
18 Attach fuel hoses according to marks and fix their new collars.
19 Join штекерные connections and fix them.
20 Establish a cover and fix it, watching thus correct position of consolidation.
21 Insert into a cover a rubber epiploon. Will put back изоляционный a floor-mat.
22 Establish into place a back seat, address to 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 up work of the index of a stock of fuel on the panel of devices.

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 gauge with the fuel pump. Then to remove the left gauge and to check up, whether the levelling hose-1 in a sediment bowl-2 is fixed. After check establish back both gauges.
