On board a small passenger vessel, fuel tank vents should _______________.
AI Explanation
The correct answer is D) All of the above.
Fuel tank vents on small passenger vessels must meet the following requirements:
1) The vent should be connected at the highest point in the tank to allow any trapped vapor to escape.
2) The vent line should have an upward gradient to prevent fuel from being trapped in the line, which could create a fire hazard.
3) The vent should terminate in a U-bend fitted with a single corrosion-resistant wire screen of at least 30x30 mesh to prevent the entry of insects or other foreign objects.
These requirements are outlined in the Code of Federal Regulations (CFR) for small passenger vessels to ensure the safe storage and venting of fuel on board.
