Question 222Motor Plants - 1st Asst/Chief70% to pass
fittings used with diesel fuel oil systems to be either flared or _______________.
AI Explanation
The correct answer is A) permitted, provided they are fitted with caps or plugs.
The reasoning for this is that the regulations for diesel fuel oil systems require fittings to be either flared or fitted with caps or plugs. This is to prevent any potential leakage or spills from the fuel system. The other options are incorrect because B) requiring separators is not a regulation for this specific fitting requirement, C) not requiring caps/plugs is incorrect as they are mandatory, and D) prohibiting these fittings altogether is too strict and not in line with the actual regulations.
