Without more backstory on the car, no.
I saw the OP was in Chicago...lots of crap weather and lots of chemicals on the roadway. Exterior rust would be expected but wouldn't necessarily have made it inside the tank, unlike a coastal car where the air itself is corrosive.

You are replacing the bolts... drill the heads off. Once they are all drilled off, take off the cover/pump. You will now have about 1/4 inch of bolt sticking up. Grab with pliers and remove.

I have yet to open any s4 tank and find acceptable levels our rust/corrosion. That includes my 100k t2 back in 06 and my first fc in 05 that only had 80k. Both had inspection plates in much better condition. But those weren't midwest cars, so we shall see...

I am experiencing the same problem described on the first post. A hard flick to the left while throttling at around 3k rpm will make my car bog for a second. My car is a NA convertible with a catback exhaust and lowered suspension. Otherwise all stock. Already changed the fuel sock and fuel filter. I looked in the engine bay and the wiring harness(es) look ok.
If I had to guess, the bog feels like the fuel pump is disconnected for a quick second. For now, I'll inspect and zip tie the fuel pump connector, the fuel pump relay, and resistor relay to prevent movement.
If anyone has any input solving this issue, please comment. Thanks.

its a known issue on the FC as the pump is on the left hand side all the fuel sloshes to the right hand side. best bet is to just keep the tank 3/4 full and replace your fuel pump strainer. try to find the OEM bosch box style and not the soft sock kind for best results.

If you think it’s electrical, tie a bit of wire into the positive leg on the connector, go drive around and see if the light goes out when the car bogs, also is your in tank baffle still there?

Appreciate the suggestions.
I have replaced the fuel sock with a Denso. Pretty sure it's the OEM replacement. If not, then it's ridiculously close. Having a full tank of gas seems to minimize the issue. It becomes more noticeable when the fuel level is at half or lower. So may not be electrical. When replacing the fuel sock, the fuel pump assembly appeared to be clean; there was no sludge or any build up. The original fuel sock did appear to have some sediment on it's screen and a small hole.
Unfortunately, it will be awhile until I work on this car. But I am curious to know if it is possible that my fuel pump has become mechanically weak or possibly clogged and doesn't have adequate fuel suction. Replacing the fuel sock usually solves this issue. Perhaps the fuel pump is not operating at full strength.
