You may want to replace the o-rings when you re-install.

Jeff is correct, always replace the injector o-rings when servicing the injectors.

You should always de-pressurize the fuel system before you remove an injector. Other wise the fuel will drain from the manifold down the opening you created, and will find its way into the cylinder. Liquid does not compress very well.

Water does not compress well. Gasoline does. I would still recomend de-pressurizing the fuel system, but isn't fuel supposed to go into the cylinder?

If you pull a rear injector out, mass quantities of liquid fuel will drain into the cylinder if you do not depressurize the rail. If the injector is returned to the manifold and now you turn the engine over, you will be trying to compress the liquid fuel and the motor doesn't like that. If the injector is working properly, a SMALL quantity of fuel is sprayed into the cylinder which turns into a vapor to be burned.
