Do you have the out of tank pump?  Your experience is
the exact oposite of mine and other posters.  I have
intank pumps (type 44) and my Bosch pump made in Czech
Republic was noisy out of the box and died within 2
yrs.  My original lasted over 10 yrs. and 200k miles
and was quieter until death than the new one was.  Two
people just recently posted that their new Pierburg
intanks were "silent".  I don't know, I haven't used
one.  I think I'd be willing to give it a shot though.
