The DU-BRO Fill It Fuel System is one of the easiest, cleanest, and most affordable ways to fuel your RC airplane. Instead of wrestling with fuel lines or reaching inside a tight cowl, this system gives you a simple and organized way to fill or drain your tank—without mess, leaks, or frustration.
What makes the Fill It system so convenient is its ability to work with four different fuel tubing sizes. Whether you use:
1/16" I.D. tubing
3/32" I.D. tubing
1/8" I.D. tubing
5/32" I.D. tubing
…the Fill It system has you covered. It’s perfect for any setup, from small glow engines to larger gasoline-powered aircraft.
At the center of the system is the Fill It Plug, which includes a large, easy-grip knob. This lets you quickly disconnect the fuel line for filling or draining—no tools required. Simply pull the plug, connect your fuel pump, fill the tank, and plug it back in. The design keeps fuel lines sealed and secure during flight.
The complete Fill It Fuel System includes:
This system is ideal for aircraft with cowled engines, where access to fuel lines is limited. It works with both glow fuel and gasoline, making it extremely versatile for many RC models.
Lightweight, leak-free, and easy to install, the DU-BRO Fill It Fuel System is a must-have upgrade for anyone looking for cleaner, faster, and more convenient fueling.
Proudly Made in the USA, it provides dependable performance and hassle-free operation flight after flight.
