some rails have a damper that screws into it , takes out the fuel pulses somewhat, looks like a mini fuel pressure regulator,

On a stock setup, there is a plug on one end and a port to attach fuel injection cleaning device etc.

On my modified setup, I have a pressure guage at one end and a fitting for a line that returns unused fuel back around to the filter after it is run thru a cooler.
