K&S KS2378 Silicon Sprint Tube for Glow Nitro Fuel D2.5xD6.5x300mm  [KS2378]

Silicon Sprint Fuel Tube

This KS2378 silicon sprint tube from K&S is an RC-scale fuel line intended for glow nitro models. The tube matches the D2.5xD6.5x300mm designation and is supplied as a single length intended for use between fuel tank fittings and the engine carburetor or clunk assembly. The component is described as silicon in the product name and is treated here as a flexible fuel line suited to typical glow fuel handling in model vehicles.

Installation is straightforward: slide the tube over the barbed fuel fitting, ensure the inner and outer diameters align with your tank or fitting, and secure with appropriate clamps or spring clips. Route the tube to avoid sharp bends, pinching points, and moving suspension or drivetrain parts. Keep the line clear of excessive heat sources within the model and trim the length to avoid slack that can trap air or allow kinks.

For tuning and maintenance, inspect the tube periodically for softening, swelling, or fuel discoloration, and replace if fuel flow becomes restricted. When replacing fuel tubing, confirm fit on both the fuel tank and carburetor side and use small hose clamps or spring clips rated for model fuel lines to prevent leaks while allowing easy service.
