PolyPill

I opened my AEM FPR to reposition the top, it hits my strut bar a bit.

It popped up more than I thought and some parts fell, I found 2, the spring and the rubber dyaphram. I don't know if there's any more, but I think there must be because now it runs like ****.

I thought I may have just messed up the fuel pressure, but when I try to adjust it my FP guage doesn't move.

Come on, some one has to have opened one up before or could do me a huge favor and open one up and tell me. I have the spring and a rubber thing with a metal half ball in the center

all that is inside is the diaphram/ball, spring, metal cap that goes on top of spring.
it sounds like you didnt get the rubber diaphram to seat just right and are getting fuel through the diaphram. Pull the vaccum line off and see if there is gas in it. if so you'll need to pull the cap and seat the diaphram in the groove.

Also, rubber side goes down...if you install it wrong it'll tear the diaphram and you'll have to have an AEM dealer order a new one.
