And why, if the pump is in the back, the noise comes from the front? Could it be the injectors instead?

Yea also known as the injector fuel pump. The normal fuel pump in the tank pushes the fuel the length of the car, the HPFP then gets it up to the pressure required for the injection system. If you have ever heard an old inductor or dewatering pump it basically makes that sounds just at a much higher frequency. they should just wrap it in dynomat lol
