Removal of air from fuel system

If the fuel tank has been completely spent or if any details of fuel system were replaced, as a rule, to delete air from system it is not required, since. It automatically leaves itself in the course of engine start.

At occurrence of difficulties in the course of start it is necessary to check up, whether fuel arrives to injectors. For this purpose at two injectors turn on накидные nuts and start the engine without preliminary heating so that fuel has arrived to накидным to nuts. Tighten nuts the moment of 20 Nanometers and again start the engine.

If air from fuel system automatically does not leave, it is necessary to arrive as follows:

PERFORMANCE ORDER

1. At work with fuel system it is necessary to fulfil requirements of observance of the cleanliness, the Rules of observance of cleanliness resulted in Section at work with fuel system.
2. Watch that diesel fuel has not got on hoses of a cooling liquid. If fuel has got, it is necessary to wipe a hose at once. The hoses damaged by diesel fuel, it is necessary to replace.
3. Disconnect the pipeline of giving (3) to ТНВД from the fuel filter. Thus compress скобу. The flowed out fuel collect and utilise it. Address to an accompanying illustration.
4. Insert a hose into a connecting carving and lower it in capacity.
5. Disconnect the relay топливоподкачивающего the pump and throw plugs on a relay socle. The pump can earn, address to Section Check of the relay of the fuel pump.
6. If fuel follows from joining, remove a crosspiece and insert the relay.
7. Again attach a hose, having greased preliminary consolidations by vaseline or the greasing which is not containing acids. The damaged consolidations replace. Fix connection by a clip.
8. Turn on on two turns a carving stopper (1) at ТНВД.
9. Turn the engine a starter so that fuel has acted from a carving stopper. Collect the flowed out fuel.
10. Tighten a carving stopper (1) moment of 25 Nanometers.
11. Remove covers at the inlet pipeline, having turned away fastening bolts. Address to an accompanying illustration.
12. Turn away all накидные nuts at atomizers the special tool, for example HAZET 4550. Turn the engine a starter so that fuel has acted. After that tighten nuts the moment of 20 Nanometers. At негерметичности tighten their moment of 25 Nanometers. It is the fastest way of removal of air from fuel system.
13. Carefully pick up in an impellent compartment the flowed out fuel.
14. Again establish engine covers.
