Sorry to resurrect this thread but I have a couple of questions on this. I have this same issue on my 04 fx4 supercrew, and the 90 degree boot is completely off of the valve, it's just hanging there. While trying to put it back into place, I checked out the photo that Manny referenced. On my intake, the back cover piece is missing. The clips up top are still there and in good shape, they just aren't clipped into anything. I can put my hand in there a ways and feel around. Does this cover hold the valve in place, thus causing my inability to see it?
Also, with the fuel rail, do I need any special tools to remove the rail from the injectors?
