Question
hi spik i have a 1996 olds 88ls since i bought the car 2 years ago the fuel pump has been huming is there any way to stop this it does affect any thing with the car just the noise is there .thanks mike.

Answer
Mike,
  The pump is supposed to mounted in rubber to eliminate any audio noise. There is a possibility the rubber has gone South. In order to check this, you will have to drop the gas tank and pull the sender assembly out.
  If you have the proper tools and a bit of mechanical ability you can do this. The best piece of advice I can give you is have the gas tank as empty as possible. DO NOT run it out of gas as this could ruin the fuel pump. Gas weighs about 7.6 pounds per gallon so the less in the tank, the lighter the tank.
  As far as the noise hurting anything else, no I don't think so. It just seems to me like the insulators on the pump have gone South. The car is 10 years old.
  Thank you for your question and I hope this helps. Please remember I'm a Parts Specialist, NOT a tech...
