Little nasty gremlins and I heard all RX-7s catch fire easily, that's why I two of them.
Seriously, they all have the potential from what I've read. Pulsation damper leaks, engine is hot, fire. That's why we all carry a fire puter outer thingy.

Most of the other things in the engine that keep this process working (oil, coolant) are also flammable.
An engine is very zerking hot, especially a rotary engine's exhaust manifold.
Leak of flammable fluid onto hot manifold = fire.
The pulsation damper is the primary cause, though fuel lines, oil lines, and coolant lines can all be responsible. Replace them *before* they fail, and you should be fine.

Also make sure you replace the hoses that go to the fuel rails and all when you replace the pulastion dampener. Mine were quite dry rotted and one was dripping some at cold starts. I replaced all my stuff so i have nice peace of mind now.

Replace the pulsation damper with a new one.
Replace the soft fuel lines in the engine bay (there are quite a few - I count 6 off the top of my head, but there may be another one) with new fuel injected rated line (expensive, but won't burst under fuel injection pressure).
Replace all the coolant hoses with new ones.
Replace all the fuel injector o-rings & grommets with new ones.
You may also want to replace the oil cooler lines. A leak here generally won't cause a fire (because it's on the "cold" side of the engine bay, down low), but a leak can make for a not-so-fun day.
Once you do all that, you've replaced basically every old part that can easily cause a fire with a new part that should last for quite a while.
