So I just got the duster together and dialing it in. Running a holley black eletric pump deadheaded to regulator. When the car is cold started the pump has a normal holley buzz/ noise that is fine. But sometimes when I restart the car after sitting ( engine still hot) I get a horrible High pitched whine from the pump. Also EVERY time after I put gas in the tank, it does the same noise untill a couple mins down the road. I'm running factory tank- 1/2 line to pump- 3/8s to filter. -6 to regulator ( dead headed) -6 to carb. I'm running no filter before the pump right now cause I thought it was a cavitation problem. And ideas. ?? Sounds like a run over cat!!
