I really dont see even an aftermarket option being a cost effective solution to a non problem. if your fuel pump is in good working condition and your pressure regulator is working properly you should not ever have such a condition that would call for the dampener. the miniscule benefit it may provide in my belief under transition is not worth the cost or development of a bigger/better unit, when simply plumbing your fuel system in "parallel" as opposed to in "series" would eliminate the need for it altogether.
I understand why mazda may have put it there in the first place but its benefit is very little on even a stock fuel system. sooner or later it simply becomes a hazard not to mention the most restrictive and weakest part of the whole system.
Btw since i first wrote this article my FPD has been eliminated and i have noticed no difference whatsoever. there is no lean or leaning conditions during injector transition that even my wideband datalogger could detect. I have no data suggesting that eliminating it has somehow affected any performance negatively or anything else for that matter. there is no problems, no difference i can tell and best of all no worries since i took it out.
