Noisy Fuel Pump 2006 Model Bus

[Aussie Steve]

My pump makes a hight pitched whining sound as it pressures up...I assumed they all did it sounds OK but I guess there is a whine and then there is a whine. I presume I am correct in thinking they are a sealed unit re the motor...I mean the bearing, if it is that, would probably only set you back a few bucks...I replaced a bearing in an evaporative air con pump cos they wanted too much for a new one and that cost about $6:00.
