saw an exploded 7 on the I-5 on sunday...
i was on my way to seattle when i noticed that there was a slow down in the traffic. also, there was this firetruck on the side with all its lights on trying to deter traffic. as i got closer, i realized it was an FC. didn't see anything else, but it looked like a bomb went off in the front. the entire hood was shot up and there were black burnt marks around the front part of the body. also, it looks like the FC left like a 20 foot mark of ice or something white on the freeway covering 3 lanes. however, besides the front, the rest of the body was perfect though. i don't really have any more details, but i just wanted to know what could have caused this? an engine fire while driving? i am currently in the market for a car or more specifically an rx-7 but seeing this last night kind of spooked me and is detering me from getting one.

I would say PD went bad, but the ice you describe makes me wonder if something went terribly wrong with an NOS system (???). BTW speaking of the PD...if you guys haven't replaced yours...DO IT! Mine went bad and I was lucky to not have my FC burned to the ground. I've seen several beautiful FC's completely toasted due to the crappy PD.

You can test it by smelling for a fuel leak, but that's like driving in a fog toward a cliff hoping you see it in time.
BTW: If you smell fuel while driving, it’s not the car ahead of you – it’s YOU!

No point in trying to test it.
If you smell fuel, find out where it's coming from.
If you're swapping your engine, replace the PD.
If you're doing intake work, replace it.
If you woke up from a nap, replace it.
Unless you KNOW your PD has been replaced, it's a ticking time bomb.

replaced his this spring and the screw was gone...

"5 engine/fuel rail"
These fail just the same....as stated by another forum member, its the actual diaphram that breaks and not the metal/plastic cover. The s5 PD has the metal covering around them but they still have the same diaphram.
is this correct?

Okay.
My engine wasn't rebuilt, it was a mazda-installed new engine.
Not to say that I trust the Mazda guys, I found an old rusted spark plug ratchet in the engine bay that definately wasn't mine, and the dude that owned the car before me only let the dealer touch the car.

cmon dudes... it's VERY easy to take off the manifold... just a few nuts and bolts and a line or two, or five here and there...
just remember where everything goes.

Instead of a screw (as found on the S4 PD) the S5 PD uses a rubber nipple/stopper, pushed through the end of the PD.
So when the rubber gets old enough the nipple detaches from the diaphragm. But unlike the S4 PD's screw, the nipple does not fall out. So you can't tell if it has failed.
Well as soon as the rubber (or screw on the S4 PD) falls out, the diaphragm in the PD no longer has the correct tension, and will soon after rip. Then it is only a matter of time before the gas starts leaking around the rubber nipple/stopper, and you have a car-b-que.

being such a well-known safety hazard, why would this part not be classified as a recall?
i used to know the definition of recall, but alas have forgotten. was there at least a bulletin (is that what its called?) on these?
