I could go 2 or 3 tanks with no noise and then all of a sudden it whines, under a little load or a lot of load. It doesn not matter what fuel i use, or how full the tank is and just as quickly as it comes it wil go. Any ideas? I am running a 650hp bosch motorsport fuel pump and larger injectors but cant understand why it comes and goes.

Is the manifold in boost or does it happen at negative pressure as well?
