What have you guys used for fuel pumps?

[David Giannandrea]

I removed mine from the 93 S4 without any special tools. You will probably
spend a bit more time breathing gas fumes while improvising without special
tools, but really, it was no problem. 

I noticed that the aftermarket Bosch pump was quite a bit lighter than the
one I removed. So I stopped, ordered the pump from Audi (additional $50),
then put the Audi-Bosch pump in the tank because 1) it weighed the same, 2)
didn't require modifications to connectors.
