DU-BRO In-Line Fuel Filter – Clean RC Fuel System for Gas & Glow

The DU-BRO In-Line Fuel Filter is an easy and effective way to protect your RC engine from dirt, debris, and fuel contaminants. Clean fuel is essential for consistent engine performance, and this filter makes sure only clean, filtered fuel reaches your carburetor—helping prevent clogs, rough running, and unnecessary wear.

This filter is built from two threaded aluminum parts, allowing you to quickly twist it open for cleaning. No special tools are needed. The inside features a fine 130-micron mesh screen that traps even very small particles while maintaining smooth fuel flow. An O-ring seal ensures a tight, leak-free connection every time.

The standard In-Line Fuel Filter measures 1.125" (28.6 mm) long by 7/16" (11.1 mm) wide and is perfect for most glow and gasoline-powered RC aircraft, cars, boats, and helis.

For larger engines or models that require more filtration capacity, DU-BRO offers the #341 Large Scale In-Line Fuel Filter, measuring 1.25" long by 9/16" wide. Both filters are lightweight—3 grams each for standard units and 5 grams for the large-scale version.

These filters work with:

• DU-BRO Medium (3/32" ID) silicone tubing for glow fuel

• DU-BRO Large (1/8" ID) silicone or Tygon tubing for gasoline

The DU-BRO In-Line Fuel Filter is easy to install, simple to clean, and built to last. It’s a small investment that provides real protection for your engine and helps keep your RC model running smoothly and reliably.

Proudly Made in the USA, this filter is a must-have for anyone who wants a cleaner, safer, and more dependable fuel system.
