Hi. Installed a standard replacement fuel pump module for my ba xr6t turbo sedan a couple weeks back
It was a Delphi branded unit from Repco (where I work)
Now after installed it started car and all good. I did notice it seemed ok then but wasn't looking for any noise.
I don't really drive the car much as my wife does but I did notice this week that there was a slight humm I could hear which I though was from engine bay but earlier my wife.got home and I walked out and could hear pump about 10 Meyers away or more. Now the noise is not a whine but rather a loud humming sound....however if I turn car off and on again it's not there for a bit it's allot quieter .....
Let it sit for 10 min then went for a drive in town (about 4 ks away) got out at shop and it was fine.....got back home and could hear it again but not as bad.
Question is can anything else cause it to be noisy ....or did I get a dud pump.im under impression of there noisy there noisy all time.
