Question 1592 Deck General

The correct answer is A) annealed tubing of copper, nickel-copper, or copper nickel. The U.S. Coast Guard regulations for small passenger vessels specify that fuel lines may be made of annealed tubing of copper, nickel-copper, or copper-nickel. These materials are approved for use in fuel systems due to their durability, flexibility, and resistance to corrosion, which are important safety considerations for small passenger vessels. The other options are not correct because plastic, rubber, or seamless steel tubing (B) are not approved materials, stainless steel, iron, or brass (C) are not the specified materials, and copper, plastic, stainless steel, or galvanized iron (D) is a mix of approved and unapproved materials for fuel lines on small passenger vessels.
