REMOVAL & INSTALLATION


See Figure 1

1. Disconnect the negative battery cable.

2. Relieve the fuel system pressure.

3. Remove any components which may interfere with the fuel rail assembly removal.

4. Unplug the electrical connector of each injector.

5. Disconnect the vacuum hose and fuel return hose from the pressure regulator.



Place a rag or shop towel over hose and tube before disconnecting.

6. Disconnect the fuel line from the rail assembly.

7. Remove the nuts/bolts securing the fuel rail. Take note of any ground cables which may be attached at these points.

8. Remove the fuel rail assembly from the engine.

9. Remove the injectors.



To install:

10. Install the fuel injectors into the fuel rail assembly (refer to the procedure outlined previously in this section).

11. Install the injectors and fuel rail as an assembly into the intake manifold. Tighten the retaining nuts/bolts to 9 ft. lbs. (12 Nm). Be sure to reinstall any ground cables which may have been attached at these points.

i highly recomend new o-ring seals for the injectors. Trust me they will leak very soon if you taken it out. Get them from honda.

and why do you need to replace the fuel rail?

I have a DIY in the DIY section but it has no more pics =/

you shouldn't have to replace the o-rings unless they're hard. if they're hard then they won't reseal, but if they're not 15 years old, they'll be fine to re-use.

i did that, and its true, but if they are hard then they would of leaked anyways.

Mine leaked a few days later and had to take it apart again to replace them. They are going to leak sooner and might as well get it done now.
