Fuel dripping from fuel rail. How to change o-rings
It is pretty standard on most vehicles it just depends on how many O-rings here is a picture an O ring on an injector. You can take a pick tool to remove the ring. The injectors should come out with some type of clip.
You can use the below just - the changing of the injectors. :)
Determine which fuel injector your Jeep Grand Cherokee will need. This
depends not only on the make and model, but also the engine size.
Models made from 1999 to 2004 may be equipped with a 2.7L OM647, 3.1L
531, 4.0L PowerTech, or 4.7L PowerTech engine. Models made after this
date can have a 3.0L OM642, 3.7L PowerTech, 4.7L PowerTech, 5.7L Hemi
or 6.1L Hemi.
Relieve fuel system pressure and disconnect the negative battery cable
with a socket wrench. Remove the air intake assembly and unplug the
electrical connectors for the alternator.
Detach the fuel lines from the fuel injectors. Remove the vacuum hoses
and electrical connectors from the throttle body with a socket wrench.
Unplug the electrical connectors for the fuel injectors, manifold
absolute pressure sensor and intake air temperature sensor. Disconnect
the ignition coils and mounting bolts for the fuel supply manifold with
a socket wrench. This will allow you to remove the manifold with the
injectors still attached. Discard the old O-rings.
Install the new fuel injectors by reversing the removal procedure. Use
a torque wrench to tighten the mounting bolts for the fuel supply
manifold to 20 foot pounds.
Start the engine and check for leaks.
