I tried to find a picture on real oem but it isn't even given a part number. It is a small cylinder that seals the top of the fuel pump to the bottom of the integrated hard line, if you have pulled an oe pump then you should know what I'm talking about. And no, it wasn't an easy diagnosis, even though it turned out to be something totally stupid. I had even pulled the pump up out of the hole just to check things, but the crack was on the backside and I couldn't see it, oh well. Carry on.
