The K&S KS2378 sprint tube is a D2.5xD6.5x300mm silicone fuel line designed for RC glow nitro use. It connects fuel tank fittings to the carburetor or clunk and is supplied as a single length for straightforward installation and service.
Fit the tube by sliding it over the barbed fitting, checking that inner and outer diameters are compatible with your tank and carburettor fittings, and secure with suitable hose clamps or spring clips. Route the hose to avoid pinching, moving parts and sources of heat, and trim excess length to keep the line free of kinks and air pockets.
For tuning and upkeep, inspect the tubing regularly for swelling, softening or fuel staining and replace when fuel flow is affected. Confirm secure fitment at both ends when replacing the line and select clamps that prevent leaks while allowing easy removal for maintenance.
