3.21. Replacement of the fuel filter


At service of components of a power supply system it is worth to remember that gasoline is easily flammable liquid in the highest measure. Do not smoke near the venue of works, do not approach it with naked flame! Immediately collect all traces of the spilled fuel, put the rags impregnated with fuel and lubricants to such place where the probability of its casual ignition is absolutely excluded! Always hold near at hand the class B fire extinguisher! Try not to allow hits of gasoline on open sites of skin - the long contact such is capable to lead to development of cancer diseases. Remember that the path of system of injection of fuel constantly is under the excessive internal pressure which has to be without fail dumped prior to work (see the Head of the Power supply system and release).

Before removal of the fuel filter it is necessary to dump pressure in a power supply system (see the Head of the Power supply system and release)!

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action!

2. This work has to be performed at the cold engine (having waited for not less than 3 hours after end of a trip).
3. On the majority of the models considered in the present manual the fuel filter is in a motive compartment of the car and is fixed on its back partition.
4. For the purpose of simplification of access to the filter, uncover the air cleaner assembled with an inlet air duct (see the Section Replacement of the Filtering Air Cleaner Element).
5. Wrap up rags the nipple connections which are subject to undocking (at a socket otpuskaniye the fuel which is under residual pressure can begin to be sprayed), prepare a stock of old newspapers for collecting the spilled fuel.

6. Having recorded a nut on the filter from a provorachivaniye, the second key weaken a hollow bolt of nipple connection of the inlet fuel line. Disconnect the pressure head line from the filter, remove and you will throw out sealing washers, - at assembly they are subject to replacement without fail.

7. Working in a similar manner, release a cap nut of the nipple socket of the final line from the lower party of the filter. Disconnect the line.

8. Having weakened two coupling bolts, take the filter from a collar of an arm of fastening of assembly on a partition. In case of need remove also an arm.

9. Fill the filter in a fixing collar and until only by hand, tighten bolts, - a certain weak point of landing of the filter will facilitate implementation of the procedure of connection to assembly of fuel hoses. Track correctness of installation of the filter: the direction of a pointer has to coincide with the direction of a stream of fuel in a path of a power supply system.
10. Connect to the fuel line to the lower party of the filter (do not forget to replace a sealing washer), screw and tighten by hand a cap nipple nut.
11. Bring the pressure head line to the top party of assembly, screw a hollow bolt of the nipple socket and tighten it with the required effort (30 Nanometers), holding the filter from a provorachivaniye the second key. Tighten a cap nut of the lower socket with effort of 35 Nanometers (again hold assembly from a provorachivaniye the second key).
12. Tighten coupling bolts of a fixing collar with effort of 14 Nanometers.
13. Connect a negative wire to the battery. Having included ignition, lift pressure in a fuel path and check power supply system components for existence of signs of development of leaks.
