Why Use an Aluminum Fuel Tank Bung Assembly?

An aluminum fuel tank bung assembly provides a stronger and more secure sealing solution compared to many standard rubber fuel stoppers. The compression-style design helps the gasoline-resistant bung expand against the fuel tank neck, creating a dependable seal for gasoline-powered RC aircraft.

The brass fuel tubes provide durable routing for fuel feed and vent lines, helping create a cleaner and more reliable fuel system installation.

Installation Notes

• Verify fuel tank opening dimensions before installation
• Use gasoline-compatible fuel tubing
• Route one tube as the fuel feed line and the other as the vent line as required by your setup
• Inspect fuel systems regularly for leaks
• Ensure fuel lines are routed away from heat sources
• Tighten evenly to maintain proper sealing pressure
• Do not overtighten; snug is sufficient for a good seal
• Pressure test the fuel system before flight

Modeler’s Tip

A properly sealed fuel tank helps prevent air leaks, fuel leaks, and inconsistent fuel delivery. Always inspect fuel lines, fittings, and the tank bung before flying, especially on gasoline-powered aircraft where vibration can loosen fuel system components over time.
