Which of the following is true regarding the fuel fill cap?

The requirement that the fuel fill cap shall be permanently attached or tethered with a non-flexible connector is grounded in safety and regulatory standards established by organizations like the American Boat and Yacht Council (ABYC). This design ensures that the fuel fill cap remains secured during vessel operation, reducing the risk of spillage and preventing fuel system contamination.

Fully tethering or permanently attaching the cap minimizes the chance of loss and helps to ensure that, when refueling, the cap doesn’t fall overboard or become misplaced. The non-flexible connector is essential in maintaining a secure connection that can withstand the vibrations and movements of a vessel in operation.

This option directly supports best practices for marine safety, as it encourages a secure and dependable system for fuel management on boats, which is vital considering the potential hazards associated with fuel spills.
