aeromtive fuel pump
When mine got noisy, and it sounded like it was vibrating itself to death,, well it did. about a week after the noise started it died. I used a holley blue for 3 years, but when you think of how many actual miles on it, maybe 300 it kinda sucks. I even have a filter before the pump. Put a second one in and 3 years later it's still going ok.
I think you're pump maybe on the way out. Can you get a rebuild kit?
