question about the inline fuel pump that comes with the drag 3
 

i have had the turbo on my car for about 3 months. since last week the inline fuel pump, has gotten exremely loud for long periods of time, but then goes back to sounding normal. i know that when a fuel pump is going bad it gets louder. i was just wondering if anyone has any ideas what else it could be. it doesn't seem to matter if i have a full tank of gas, or a quarter tank it will still do it.
