Question 1932 Deck General

The correct answer is D) a separate sounding tube or an installed marine type fuel gauge. The Small Passenger Vessel Regulations state that if it is impractical to use the fill line to sound the fuel tank, the tank should be fitted with a separate sounding tube or an installed marine type fuel gauge. This allows the operator to accurately monitor the fuel level in the tank, which is important for safe operation of the vessel. The other options are incorrect because: A) a glass tube may not provide an accurate reading, B) an extra reserve tank is not a substitute for being able to monitor the primary fuel tank, and C) while a good air vent is important, it does not allow the operator to directly monitor the fuel level.
