What is a magna-stick?

• A. A magnetic air filter device.
• B. A type of fuel dipstick kept permanently in the tank.
• C. A sensor for fuel pressure.
• D. A gauge for oil level.

Answer: (B)

Magna-stick is a fuel quantity indicator that stays inside the tank as a permanent dipstick. A float follows the fuel level and, through a magnetic linkage, its position is read by a gauge or scale in the cockpit. This lets you quickly see how much fuel remains without removing hardware or using external probes. It’s not related to an air filter, fuel pressure sensor, or an oil level gauge, which is why those other options don’t fit.
