Can we talk fuel pulsation dampers????
Whats the deal with the pulsation dampers??? What exactly do they do and how many of you guys had one go bad? When it goes bad should it be replaced with a oem, aftermarket, or can it be removed completely???
Thanks,
STEPHEN

I pulled out my old recipet just to be sure. I paid $97.09 for a PFD from Mazdaformance. www.mazdaformance.com
It lists for $129, but they can sell Mazda parts with a %25 discount, or something like that. They're awesome to deal with.

The pulsation dampner compensates for any irregular pulsations in the fuel flow to ensure the fuel injectors constantly have flow. Well..................that's my theory anyways 
You know, people always take them out when they upgrade their fuel system. I'm sure it is an absolute when dealing with the stock fuel pump, but when we upgrade to a higher flowing pump, I really don't see the need for it. Again, that is just my theory

thats not paint....
Flybye has the right theory. If you have the stock stuff replace it. It goes bad from this rubber piece for **** that hangs out the top. That usually gets brittle, cracks, and leaks. Not good to drive unfixed, thats asking for an engine fire.

But you guys think with a upgraded fuel system that I can ditch it? i dont know I might replace it just to make sure. My local dealer will sell it to me for $108 so I'll prob do that. I know its a little more than online prices but not much and I dont have to waite for it.
Does anyone know FOR SURE that its ok to ditch???

Look at it this way.
The fuel pulsation dampers seem to be failing because on the 3rd GEN they are now approximately 10 years old. Apparently that is going to be their normal life span.
Just replace the FPD and don't worry about it for another 10 years.

Ralph at Xcessive Motorsports by Portland, OR. He put in a huge fuel pump, fpr, and new injectors. They also fabbed up the fuel lines for the fpr, don't know the details on that though, sorry.

An SX fuel pressure regulator will act as a fuel pulsation dampener.
