metal shavings in gas tank

I have a 93 yj with the 20 gallon plastic tank, 4L engine. While I have it apart I looked inside and noticed metal shavings in the tank. The metal fuel lines have never been messed with. It isn't in a quantity I would associate with vandalism.

My question is if it could have possibly gotten in there via the fuel return line.

My current theory is that they are the end result of 20 years of shoving a gas nozzle into the filler tube. A second thought is that maybe a gas station pump somewhere was having issues.

My jeep runs in a more tired fashion than it did 10 years ago, but I don't think this has anything to do with it. However, I submit these observations to you all just to see if I could be missing something.

After 20 years I am sure we could guess all day. If they metal you can get most with a magnet. Flush the tank and dry it out should be fine.

I agree on both the unlimited scope of speculation and the solution. The shavings weren't magnetic, but tape worked fine. I was asking more about if there could be any options that came from upstream that could be correlated with having less power.

Not that I know of but while it is apart blow out the feed and return lines if you have a compressor.

I found aluminum shavings in my 95 YJ tank back when I did my first engine swap. I cleaned them out and have not found any additional shavings the 3 times that I have been into the tank since.
