You kidding?

[lesstatt]

Yes it should be on all the time............... name gives it away really, if it stops then it stops pumping fuel and then engine stops, dont know if you should hear it, mine sometimes whirrs and clicks sometimes not, been doing it for 3 years so im not too worried

May be its a bit worn then,just seems louder than normal.Im aware of it when driving.

Did you finally get round to cleaning your ears?

Same happened with mine over the weekend, went for a blast, when I got back I noticed that the fuel pump sound had changed from the normal quiet hum to quite a loud buzzing.

Drove the car this morning and it had returned to normal.

If it runs all the time it uses a lot more fuel

A noe for a more sinsible reply.

My pump sounds louder when there is less fuel in the tank, about 1/4 of a tank. I don't think it is sucking air it must just be the lesser weight of fuel in the tank having an effect on the pump.
