I'm trying to clean the fuel tank of my 1993 Audi 80, (renamed as Audi 90 in the U.S.).

First of all, does it come out? Does it come apart somehow, because it's bigger than the hole/opening on the fuel tank?
What about the little switch-thing on its right side? What is it for?

Recently my 5cylinder 1991 Audi 90 has been stalling shortly after I get going. If I push the gas pedal to the floor it runs good until I release the gas pedal. Usually within 5 minutes it starts to run normally and is good until I shut the car off and restart it. Any ideas?
