I used to plug them until I got cracks in a fuel cell. They said it was from pressure that builds up in your hot car - over time. Now I plug a tube in and put it down into a 4 oz. plastic bottle. It has a pinhole in the top to let air come in and out. Works in both directions. It also catches what might spill. On smaller single fuel cell jets it can also serve as the overflow tank when filling.
