Default Possible fuel pump issue?

I've noticed that my bugeye is experiencing some hesitation after 3500 rpms. it seems kinda like it's starving for fuel... my AFR is a little low at WOT, but is right about 14.7 any other time which I would expect. I cleaned my MAF and it didn't help. according to accessport, my fuel pump is at 100% duty before I even reach WOT. could this be my issue? could it be a fuel filter maybe? I'm kinda lost when it comes to fuel management.
