I'm replacing the fuel pump on my 89 90q after my programming final (love t=
he audi gods' wrath during finals week).  Is there anything that I need to =
know other than disconnecting battery and having the bentley for this job? =
 Will I need something to plug fuel lines, special tools, etc?

Also, The howling noise that I thought was coming from the fuel pump isn't.=
  It begins after the car has run for a couple of minutes but the heater fa=
n hasn't yet come on.  I was parking my car when the noise came last week a=
nd when I shut it off, the noise died away.  I started it back up and the h=
owl was there again.  I turned off the climate control (digital one) and th=
e noise promptly went away.  I experienced the noise a couple more times wh=
ile driving later on last week, but could always get it to go away by turni=
ng off the climate control.  Ideas?

TIA,
