For some reason the rubber diaphragm keeps ripping on my FPR. This is my 5th one already. How much pressure is the diaphragm rated to? I spiked yesterday after putting in a brand new one. Also, for those who don't drive their S everyday, I called AEM and they said that it can happen if fuel is stagnant on the diaphragm for too long. Anyone else experience this?

Thanks.
