Nah, the part is designed to last 10 years or 100K miles. If it breaks after that, the NTSHA says that it is a maintenance item.

Now if there were a considerable amount of failures (probably more than 50-100 examples) under 100K miles and under 10 year, then there would probably have been an investigation and possibly a recall.

 

where is the PD? I have both of my intake manifolds off, so i'd like to replace it while im at it. i really cant afford to have my car burn to the ground. Pictures would be nice. Thanks

The PD is always an issue. And yes, if you have a J-Spec engine with only 30K miles on it you STILL need to replace the PD. Regardless of mileage, the engine AND PD are still 15+ years old.

The S5 rails still do fail, i've read many an article and thread on it. Maybe not as often, but i still wouldnt want to take that risk.

The PD is still a necessary part of the fuel system. Mazda put it there for a reason, thus it must serve a purpose. Just because a banjo bolt works, doesnt means it works PROPERLY. (i.e. slight pulses in your injectors, instead of a smooth fuel flow, can result in improper A/F mixture. Possibly leaning out slightly, under boost can result in that all to familiar "pop")

When everything in your car (especially the fuel system) is tuned up ever so exact, and the difference between a blown motor and better E/T's relys on your A/F mixture being just right... its just not a risk id like to take
