Great, thanks for that info.
Below is fuel pump removal/installation procedures for your 1999 Audi A6 Avant Quattro.
Please note, there are different versions of the fuel system for this vehicle. If your vehicle is not equipped with the access panel, it means that your fuel pump is located inside of the tank. If this is the case, please let me know and I will post correct instructions.
CAUTION:
Determine the correct radio anti-theft coding before disconnecting the battery.
REMOVAL:
With the ignition switch off, disconnect the battery negative cable.
Remove the fuel pump access cover in luggage compartment floor
((Fuel pump access cover removal))
Disconnect the harness connector, fuel supply and return hose from the flange.
Remove the ring nut with spanner wrench.
Remove the flange and sealing ring from the fuel tank opening.
Loosen the fuel pump module from bayonet connection by turning it to the left and removing it from the tank opening.
CAUTION:
If the fuel pump module is still filled with fuel, empty before installation.
INSTALLATION:
Installation is in the reverse order of removal procedure.
Note the following during installation:
When installing the fuel pump module, make certain the fuel sensor arm is not bent.
Lubricate the flange seal with fuel before installing.
Ensure the proper installation position of the fuel pump module flange and attaching parts, as shown.
When the fuel pump module is correctly installed, the fuel gauge sender points to the direction of travel 'A', as shown below.

Thank you for the prompt reply.
My car (1999 A6 Quattr Avant) uder rear set has two covers, for the pump on the right and for sender on the left. I am worhing on the right one - pump. So far I unplugged the battery, drained gas from the tank, opened cover one the right, disconnected power connector, disconnected outgoing and incoming fuel lines, removed ring nut, removed flange and seal, disconnected two more connectors and stuck here. I cannot pull the pump out - I figure I need to turn counter clockwise, but it appears that there is some latch It does not want to go and I do not want to force it. Is there anything that needs to be pushed or any special tool?
Thanks, Konstantin.

My sources do not state any special tool or any other component that is holding it in. It should turn left (counterclockwise) then pull straight out if you have disconnected everything correctly.
