I want to replace my fuel filter, and I figure as long as I am depressurising the fuel system, replace the spark plugs too. I read that pulling the connector off the fuel pump relay switch in the trunk and then letting the car run dry is a way to depressurise. Is this the best way or is there something else I can do.? Also, has anyone had any problems with fuel leakage after popping off and back on the fuel rails?

That way will work and you won`t need to pop off the fuel rails to change the plugs.

How do you remove the coils without removing the rails? It appears at least from looking at it that the fuel rails are blocking the removal of these. Forgot to mention I have a 2002 GT.

Theres a 7mm screw holding down every coil pack. Remove the screw and turn and pull off the coil pack.

I had this same question, the coils just have a flexible rubber boot on the bottom, they can be pulled from under the fuel rail with no issues. You -may- have a schrader valve on the passenger side fuel rail... However Ford removed this at some point (mid 01 I think) because they figured we didn't need to depressurize the fuel system...? The reason for removing it is unknown to me but it's frustrating. Me? I can just remove the fuel line from my nitrous nozzle, put it into a cup, and open the solenoid

You can also remove the two screws holding the fuel rail down, and not disconnect them from the injectors if you need a little wiggle room. I have wider aftermarket fuel rails so that makes it easier to get a socket in there.

i have to say, changing plugs in the new edge is a breeze. just pop the coil pack off the plug and lift it up until it hits the fuel rail. then simply bend it out to you. takes about 10 seconds to pop it off. alot easier then you think.

Getting covered in Fuel is part of the fuel filter changing process. Its tradition.

Agreed. Just take off one of the lines to the pump, and catch what comes out.

you dont need to depressurize the fuel system. just let it come out or clamp the hoses. also dont forget there's stil fuel in the filter and it can/will spill out
