Why Built-In Fuel Barbs Matter for RC Fuel Systems
Fuel tubing slipping off the tank is a common cause of engine failure in RC models. The Du-Bro 408 tank solves this with integrated fuel barbs on the clunk stem. These barbs grip the tubing firmly, even under the vibration and pressure typical in high-performance RC vehicles and aircraft. This design reduces the chance of fuel starvation or leaks during flight or runs.
Setting Up the Du-Bro 408 Fuel Tank
Installation is straightforward because the tank comes with all required hardware. The one-piece clunk is pre-assembled with fuel barbs, so there’s no need to source additional fittings. Simply mount the tank, connect your fuel tubing, and secure the lines. The tank’s metal exterior withstands pressure from pressurized fuel systems without cracking or splitting.
Common Questions Answered
Can I use this tank with gasoline?
Yes. The Du-Bro 408 tank is compatible with both glow fuel and gasoline when you add the Du-Bro #400 Gasoline Conversion Stopper (sold separately). This stopper allows safe switching between fuel types without replacing the tank.
Does the tank include a clunk?
Yes. It comes with a one-piece clunk that has fuel barbs built directly onto the stem. The clunk moves freely inside the tank to pick up fuel regardless of orientation.
What is the exact capacity?
The tank holds 8 ounces (236 ml) of fuel, suitable for many medium-size RC aircraft and vehicles.
Is the tank pressure-resistant?
Yes. The Du-Bro 408 is designed to withstand vibration and pressure without splitting or cracking, even when used with pressurized fuel systems.
