Injection whine

My latest GT, fitted with fuel injection has a rather annoying whine........well more like a screech!!

The noise starts on tick over and is fairly loud and only eases off slightly when the throttle is pressed, ie under accelerate. Once the throttle reaches a constant position the noise return and needless to say I'd like to sort it out.

The noise sounds like it's coming from somewhere around the injection manifold, injector area but has anyone got any idea's, am I looking at an injection strip done or could it be a little more simple?

It almost sounds like a vacuum leak that is acting as a whistle.

I'm still sorting out my own injection system and rust that got into it, so good luck.
