s13 w/blacktop sr20det, walbro fuel pump and z32 fuel filter.

Every time I would turn the key in the ignition, I would hear the whine of the fuel pump before starting the car. Just a couple of days ago I noticed that my fuel pump sounded very weak as if the battery was almost dead but it wasnt. I could still turn on my car and drive but Sat. as I was driving to the track, the car would hesitate and not let me rev (pressing the gas pedal did nothing) and then go back to normal and then do it randomly.

I checked the fuel pump fuse, the wiring to the fuel pump seems good, so I am thinking it is probably a clogged fuel filter? Would a clogged fuel filter turn the fuel pump whine into a weak sound as if a lot of fuel isnt getting pumped?

Possibly my fuel pump might be bad?

Any input would help greatly before I buy something that isnt necessary. Thanks in advance.
