This is a replacement stainless steel gas cap for Southco's pop up deck fills. The optional locking version uses the unique Orcas tubular splined key, for added security. Two different sizes are available based on the barb size of your deck fill, either 1.5" or 2" diameter. Each cap comes with a security lanyard, which will hopefully help keep your new one from going overboard.
