Attention! See the warnings at the beginning Depressurizing the supply system.
Withdrawal
1. Disconnect the negative cable from the battery.
Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to put the equipment into operation!
2. Relieve pressure in the supply system (see Depressurizing the supply system).
3. Disconnect the wiring from the injection injectors (see accompanying illustration).
4. Disconnect the vacuum hose and fuel return hose from the pressure regulator (see Removal and installation of the fuel pressure regulator).
5. Disconnect the ground bus from the fuel line.
6. Disconnect the fuel supply line from the fuel line.
7a. Give fixing nuts (Civic) and remove the fuel line from the injection injectors.
7b. Fixing nuts (Integra).
8a. Remove the injector (s) from its seat in the intake manifold.
8b. Remove and discard old o-rings and damper rings (see accompanying illustrations).
Note. It makes sense to replace all rings used in injectors, regardless of their condition.
Installation
Attention! In order to reduce the risk of damage to the O-rings, the injectors should first be filled into the fuel line and only then the assembly should be installed on the intake pipe.
1. Lubricate the new damper rings with clean engine oil and put them on the injection injectors.
2. Install new O-rings (also lubricated with motor oil), then fill the injectors into the fuel line (see accompanying illustration).
3. Lubricate with impellent oil new landing sealing rings and plant them in nests under installation of injectors in the inlet pipeline.
4. Establish assembly of a fuel highway with injectors on the inlet pipeline. Tighten the fixing nuts to the required torque.
5. Further installation is carried out in the reverse order of dismantling.
6. Having finished the installation, without starting the engine, turn on the ignition in order to activate the fuel pump for a couple of seconds and raise the pressure in the power system. Repeat this activation two or three times, then check the fuel lines, lines and injectors for signs of leaks.
