Wouldn't mind seeing the TSB, if anyone has a copy.

There aren't any screens in front of the pump on the ur-quattro - Audi
deleted the sediment trap via TSB as well.  The problem on this car
is that the intake is on the bottom of the pump - my Passat had an
in-tank pump, but it was screenless and sat in a basket that performed
that function.  There was crud underneath it when I took it out,
but plenty of clean sidewall screen for fuel to flow through.

It's blocked again, despite careful tank cleaning.  It's coming out -
you can't have a car that mysteriously stops every few hundred miles.
