Help! Injector Question

[key_on]

I'm elbow deep into my injector replacement project. Plenum is off and everything went well with that. Two questions:

1) While loosining the screw for the ignition module, the 1/4 inch socket popped off and fell somewhere. Haven't been able to locate it with a magnet. Can this thing get anywhere that will cause damage if not located?

2) I've removed the four 10mm bolts that hold the fuel rails on. Does the whole thing just pull off, or do I need to remove something else. Everything still seems tight, so I don't want to pull on something if I need to remove something else first.

Thanks in advance for any quick replies.
