Full Blown called. The pump housing was installed the 'wrong' way.

It turns out that FB designs their hangers such that the fuel inlets/outlets point forward toward the engine bay. This would place the slits in the cup to the back of the car. That actually could be enough to keep fuel from escaping as readily since during braking or turning the fuel would hit the solid parts of the cup.

All perfectly logical, other than the fact that the stock hanger isn't oriented that way and the hanger came with no instructions. lol.

I'm going to go pick up the car after work...I'm thinking I'll take it for the evening and find a big parking lot to perform some manuevers in to test it out.
