Question 1950 Deck General

The correct answer is B) In both diesel and gasoline installations. This is because flexible hoses are permitted for use in both diesel and gasoline fuel lines on small passenger vessels, as long as they meet the applicable safety standards and regulations. The use of flexible hoses helps to accommodate vibration and movement in the vessel's structure, which can otherwise lead to leaks or failure of rigid piping. The other options are incorrect because C) prohibits the use of flexible hoses in both diesel and gasoline installations, which is not accurate, and A) and D) restrict the use of flexible hoses to only one type of fuel, which is also not correct based on the regulations.
