I don't know if you have the "intank pump" or not.
Reports so far are that the Pierburg pump is
absolutely silent.  I think considering it's actually
LESS money, at least where one of our listers found
it, that it'll definitely be the next pump I put in my
car.  Still made in Germany, unlike it's Bosch cousin.
