I had a leaking BBK unit. Called them up and was told to remove the FPR and tighten the allen screws that hold the two pieces together. That solved the problem, although I just recently replaced it with an Aeromotive FPR. Make sure the FPR mounting surface on the fuel rail is not bent. Put a little light oil on the O-ring before you install it, and make sure that the 3 screws holding the FPR are tightened down, also check to see as you're tightening the unit down that the flat gasket is seating properly.
SMOKEDAWG - My experience has been that I needed to remove the upper and the fuel rail to easily get at the allen screws for the FPR, although the instructions indicate that you don't need to do this.
