Are the s4 turboII and N/A fuel pulsation dampner the same or are they not compatible.

 

they are the same

 

you are better off replacing it with a banjo bolt. the bolt size is 12x1.25 i have done it and noticed no ill effects.

pay no attention to the last post, mazda engeniers installed the pulsation dampeners to equalize pressure to each fuel rail and fuel injector, with out the pulsation dampener the secondary fuel rail may have a fluxuation in pressure that cuases a lean situation in the combustion chamber ultimatly causing detenation that cracks your apex seal.....just get a new or use one that is functional.

 

Why is this thread titled fuel pressure regulator?

 

yeah is the guy asking about a Fuel pressure Reg or a PD???

 

The title was a typo. He knows the difference b/t the fpr and the pd. He's read the online fsm and up to speed on fpr's and pd's.

 

Wow thanks?!? Sorry it was a typo. HAILERS do i know you? How did you know all thet about me. What part of fort worth are you from?

 

Series four are all the same: See http://www.mazdatrix.com/c-pulsation.htm

Nope, don't know you. Just a lucky guess and messing around with some of the other responders.
