Check for leakage in engine bay none check under the car for leakage still can't find it its the tank.

no tune stock ecu its probably running rich,i have a aeromotive fpr set to 43.5

i may be wrong, but i think when the bov isnt recirculated it causes the ecu to confuse fuel and makes it run rich.

yes ill do that i dont think the injectors are leaking because i dont really see fuel in engine bay or near the intake mani

It could also be the o ring in the tank or the upper gasket in the trunk too

If you replaced the ff parts for aftermarket ones i suggest to get new gaskets for them:
Fuel pump- housing plate o-ring gasket
Fuel injectors o-ring gaskets
Fuel filter- check for loose clamps or cracked hoses
Lastly check fuel tank and fuel hoses for leaks and cracks

Hope this helps
