ok there is a DIY on how to install the bosch 040. They are a good pump, but i dont know what you lot are complaining about the priming noise. ALL good pumps will make the noise when u turn the key on. My 040 humms all the time, i have done the 14v mod to it too.
Just cause ur fuel pump makes a noise it is in no way stuffed.
