I was trying to hunt down some rattles in my car, and found this guy.



What is this cap for? Should I put it back on or just toss it?

Okay, I was wondering what the fpr thing is. I imagine its to keep that thing clean, but the cap no longer fits - probably warped from heat. I guess I'll get a new one from the dealer.

If you have a heat gun, heat it a couple of times until it goes on, if not try running some hot water over it.

That is the fuel rail pulsation dampner or muffler. It does vibrate a lot, but smoothes the fuel stream since the fuel pump sets up fuel pulses.

The fuel regulator is actually to the right of the fuel rail dampner.

i knew it wasnt the fpr, i just couldnt remember what it was called, so its the fprd, gay

It's a pulsation damper, which is supposed to make the injectors less noisy.
