Your picture isn't working for me but what you're talking about is probably the fuel damper. On one side of the rail you would have the pressure regulator which has a hose coming off it as a fuel return line. The other side has a hose going to it which is the feed line and it goes to a fuel damper which regulates pulsing of fuel as it enters the rail.

It it has a plastic cap on it

Ok, like I said...

It it has a plastic cap on it
The best clue yet: plastic cap. That is a test port for the technician. You can test fuel pressure here or attach a fuel injector cleaner here.
