Those small chains are not that difficult to get back into the filler tube. Turn the cap upside down and coil the chain around the inside of the cap then put the cap on.
As I said above, ours have a metal rod attached to the end of the chain. The length of the rod is longer than the diameter of the filler tube opening. We have to feed the rod in before the chain. The rod is supposed to wedge against the bottom of the filler tube to keep the fuel cap in place.
