ABYC Diesel Practice Exam

Which type of fuel indicator is permitted according to ABYC standard H-33?

1. Analog gauge

2. Dipstick

3. Temperature gauge

4. Pressure gauge

The correct answer is: Dipstick

The ABYC standard H-33 specifies that a dipstick is a permitted type of fuel indicator for marine applications. This is primarily due to its reliability and simplicity in providing a direct measurement of fuel level in the tank. The dipstick allows for accurate readings, enabling boat operators to assess the amount of fuel remaining easily, which is crucial for safety and operational planning during voyages. On the other hand, while analog gauges are commonly used in many vehicles and equipment, their accuracy can be influenced by factors such as fuel slosh, positioning, and calibration. Temperature and pressure gauges, while valuable for other measurement contexts, do not provide a measure of fuel level and therefore do not meet the requirements outlined in ABYC for indicating fuel contents.
