the FPD and FPR are two different things. Some people say you dont need it, others will disagree. Mazda put it there for a reason. I personaly kept mine.

As the injectors open and close they can cause a pulsation in the fuel rail, the FPD helps to 'Dampen' that pulsation for an even flow of fuel to the injectors
FPR = Fuel Pressure Regulator
Regulates Fuel pressure...

It's really hard to say. It stands to reason that Mazda put it on there for a good reason, and the 787B Lemans car even had a pulsation dampener on it!
This has been debated ad nauseum. Without someone doing a back-to-back test with the pulsation dampener and a bypass on a wideband, there's no good way of knowing what the result would be. Many people who have bypassed it have done so with cars that were VERY not stock, so that's hard to compare to.

I just replaced mine even though it looked tip-top -- I didnt want to risk it going out and since there is so much in the air about how safe it would be without one I chose to just replace it.
Actual replacement wasnt too bad -- took me 5 minutes after I got the rat nest out of the way.
