DUBRO REBUILD KIT: 334 FUEL VALVE

The DU-BRO Fueling Valve Rebuild Kit is the perfect way to restore smooth, reliable operation to your DU-BRO fueling valve without replacing the entire unit. Over time, fuel valves can wear out due to use, vibration, and exposure to gasoline or glow fuel. This rebuild kit gives you all the essential internal parts you need to bring your fueling valve back to like-new condition.

Inside the kit, you’ll find the key components that keep your fueling valve working properly:

• 2 replacement O-rings

• Shuttle (internal sliding piece)

• Spring

• Lock washer (included with #718 and #719 kits only)

• Nut

These parts restore proper sealing, smooth movement, and consistent operation so your fueling valve performs just as it did when new. Rebuilding your valve ensures clean fueling, prevents leaks, and helps keep your fuel system reliable and safe.

The kit is easy to install, even for newer RC hobbyists. Simply disassemble your fueling valve, replace the worn parts with the components from the rebuild kit, and reassemble. In just a few minutes, your fueling valve will be ready for many more flights.

Whether you use DU-BRO glow or gas fueling valves, the rebuild kit is a smart, affordable way to extend the life of your equipment and keep your RC aircraft fuel system operating smoothly.

If your fueling valve is starting to leak, stick, or feel loose, the DU-BRO Fueling Valve Rebuild Kit is the quick and reliable solution.
