It is unlikely the filter is defective, but assuming the pump is not
failing, the buzzing is probably caused by the inlet being restricted.
There is a screen in the tank. This screen is probably clogged with dirt
and rust. It can not be serviced so plan on a future tank replacement.
Continued operation this way can cause drivability problems and will
eventually destroy the pump.
