Attention. Observe fire safety regulations.
Withdrawal
1. Disconnect (-) battery cable.
2. Relieve fuel pressure (see above).
3. Disconnect the fuel injector connectors, EGR valve, remove the carbon filter purge control e / valve, remove the PCV valve, disconnect the additional vacuum tube.
4. Disconnect the vacuum tube and fuel tube hose from the pressure regulator. Cover the regulator with a cloth before disconnecting the hose.
5. Remove the two nuts securing the fuel pipe.
6. Remove the fuel pipe.
7. Remove the intake manifold and fuel injectors.
Installation
1. Install the ring cushion on the fuel injector.
2. Install the O-ring, lubricated with engine oil, into the fuel injector groove. Install all 4 injectors to the fuel rail.
Caution: Be careful not to damage the O-rings when installing the injectors to the fuel rail. Insert nozzles without distortion at a right angle.
3. Install O-rings lubricated with engine oil on the intake manifold.
4. Install the fuel rail assembled in step 2 on the intake manifold.
Attention: In order not to damage the injector O-rings, the injectors are first installed on the fuel rail, and then the whole assembly is installed on the intake manifold.
5. Tighten the fixing nuts of the fuel pipes.
6. Connect the vacuum tube and fuel tube hose to the pressure regulator.
7. Connect the connectors of the fuel injectors, the EGR valve and the charcoal filter purge control solenoid valve, install the PCV valve, attach an additional vacuum tube and install the charcoal filter purge control solenoid valve.
8. Connect (-) battery cable, turn the ignition key to the ON position (II) (do not turn on the starter). In this case, 2 sec. the fuel pump turns on and the pressure in the fuel pipes and high pressure hoses rises. Repeat this action 2-3 times and check for fuel leaks in various parts of the fuel system.
- Be sure to replace O-rings, O-rings and O-rings after disassembly.
- Coat o-rings and o-rings with engine oil before installing them. Never apply brake fluid, coolant, vegetable oils or alcohols to them.
