What do go-no-go fuses do?

• A. They regulate fuel pressure
• B. They shut off the fuel if the first and second stages fail to separate contaminants from the fuel
• C. They monitor temperature
• D. They act as a filter element

Answer: (B)

Go-no-go fuses are safety interlocks in fuel purification systems. They verify that the fuel has been properly cleaned by the filtration stages. If the first two stages fail to remove contaminants from the fuel, the go-no-go fuse trips and shuts off the fuel flow. This prevents contaminated fuel from reaching the engine and causing damage. They aren’t about regulating pressure, monitoring temperature, or acting as a filter element; they serve as a safeguard to ensure fuel cleanliness before it can be used.
