The K&S KS2378 silicone sprint tube is an RC fuel line sized D2.5xD6.5x300mm intended for use on glow nitro models. It is supplied as one length to connect tank fittings to the carburetor or clunk assembly and is built to handle typical model fuel handling.
To install, slide the tube onto the barbed fitting and verify correct inner and outer diameters for your tank and carburetor connections. Secure the tube with properly rated hose clamps or spring clips, route to avoid tight bends and moving parts, and keep it away from heat sources that could soften the material.
Inspect the tube during routine maintenance for signs of swelling, softening or fuel staining and replace if flow is impeded. When fitting a new line, double check fitment at both ends and use small clamps to prevent leaks while keeping the assembly serviceable.
