hey folks. i just got my sr back on the road. i have noticed that my walbro 255 fuel pump has gotten progressively louder over the past four days(im pretty sure-or are these things just that loud?). it's like a loud humming/buzzing sound. what could be my problem and/or what has caused this. i purchased the pump brand new. this is my setup:
