This 2-foot blue silicone fuel line is designed as a practical replacement for worn or hardened fuel tubing on nitro-powered RC vehicles. Made from fuel-resistant silicone, it maintains its flexibility and sealing properties even after prolonged exposure to nitro fuel, helping to prevent the cracking and hardening that commonly causes older fuel lines to leak or restrict flow. The tubing features a 3/32" inner diameter, which matches standard fuel fittings found on most 2-stroke nitro engines, including those used in RC cars, trucks, buggies, and other hobby models. Its smooth inner bore supports consistent fuel delivery, while the flexible outer wall allows easy routing through tight engine bays without kinking. Installation is straightforward – simply cut the fuel tube to your required length with scissors or a hobby knife, then push it onto the fuel tank outlet and carburetor inlet. The elastic silicone grips fittings securely to minimize the risk of leaks or air intrusion. This 4-pack gives you two full feet of tubing per piece, offering ample material for routine maintenance, repairs, or custom fuel line routing on multiple RC models. The blue color adds a subtle visual accent that can help distinguish fuel lines from other tubing in your engine bay.
