2. Mark the wiring harnesses from the injectors.
3. Place a rag under the pressure regulator. Disconnect the fuel hose and fuel line. Plug the fuel line.
4. On Prelude, disconnect the fuel hose from the fuel line.
5. On Prelude, remove the EACV valve from the intake manifold.
6. Remove the fuel line mounting nuts and wiring harness.
7. Remove the fuel line from the injectors, leaving them in the intake manifold.
8. Remove the injectors and seals from each manifold port.
9. Remove the shock absorber and sealing rings from each injector.
To install:
10. Install new shock-absorbing rings on the injectors. Install new sealing rings on the injectors and coat them with a thin layer of clean oil.
11. Insert the injectors into the fuel line. Make sure that the sealing rings are not damaged.
12. Coat the new seals with a thin layer of clean oil and install them into the intake manifold.
13. Install the fuel line and injectors into the intake manifold. Before installing the fuel line, make sure that there are insulators on the mounting bolts.
14. After installing all injectors into the manifold, align the center marks on the injector electrical connectors with the marks on the fuel line.
15. Install the fuel line mounting nuts and tighten them securely. Make sure the harness is secured in its clamps.
16. Connect the vacuum hose and fuel hose to the pressure regulator.
17. On Prelude, connect the fuel line to the fuel line.
18. Connect the connectors to the injectors.
19. Turn the ignition switch to the ON position, but do not crank the starter. After the fuel pump runs for about two seconds, the fuel pressure in the fuel line will increase. Repeat this two or three times, then check for fuel leaks.
20. On Prelude, install the EACV valve on the manifold.
