Ive just bought a 1999 v8 Discovery, there was a whining noise coming from the ace pump on low revs, I was told this was normal, but i cant see how it is, had the pump changed for a nearly new one, it was perfect for about 5 miles then noise came back, hadd another second hand one fitted today and the noise is worse, has anyone any ideas? Thanks

 

You might want to send me you tele number and a good time to call, I think I can walk you thru this issue.
