A length of chain was found in the tank when replacing decaying fuel line. I remember reading about a reason to put some in the tank but can't remember what it was. Hoping somebody's memory is better than mine.

You do that to knock rust and other crap loose in an old cruddy tank.
I doubt there is any "fermentation" going on in a gas tank. There is a chemical reaction which will render your fuel line useless and a mess in your gas tank.
I guess what's happened here is that during a body-off restore/engine change 16 years ago by a previous owner the chain was put in the tank when it was removed and then it was manhandled around to loosen up any crap and crud, then drained (hopefully) but the chain was forgotten and left in. I didn't think it would give me any performance gains but thought it might be safety issue at the track or something like that.

And maybe somewhere along the line somebody wanted to play a trick on the then owner and slid a length of chain through the filler cap. Then you have a mysterious noise from that point forward. Much like disgruntled autoline workers that sometimes would wire a can filled with nuts & bolts to the inside of a fender.
Crazy place to keep a tow chain..............

My grandfather bought my grandmother a Lincoln one time back in the 60's. He got the car dirt cheap because it has a clunking noise that the owner could not figure out. My grandfather looked and looked and couldn't figure it out either. My grandmother drove that car for quite a while from what I understand. She had six kids so she was pretty good at ignoring sounds...lol. Long story short the driver window got broke out(by one of her kids) a few years into owning the car. When they picked it up from the shop the glass man handed my grandfather a bill and a wrench.
The guy told him he found the wrench inside the door when he pulled the panel off. Clunking sound was gone.

Unless the sugar ferments and turns to alcohol, thus providing a higher octane fuel.
Sugar is not soluble in gas,it actually "clumps' together in little "balls" and if you put enough in a gas tank, it will "smother" the sock on the end of the fuel pickup in factory cars,starving the engine for fuel......
You can pour sugar directly down your carb on a running engine with no ill effects on the engine, the only thing it will do is make your exhaust smell sweet.........
Have witnessed this in a training seminar!!!!!!!!!! we put 5 pounds of sugar in the gas tank of an early 80's chevy carbed truck and let it run,then when nothing happened,the instructor popped the hood on the truck,took off the air cleaner and began pouring sugar down the carb while the truck was idling,he did this on/off for 5 minutes,nothing happened......he used the same old truck for demo purposes numerous times.......
I heard that when the sugar gets heated in the cylinder it turns to toffee and clags the inlet and exhaust valve and leaves toffee on the piston? Never tried it and never will.
