Fastrax RC Fuel Filters & Clunks for Nitro Models

Keep your nitro or petrol RC engine running clean with our range of in-line fuel filters and tank clunks. Choose from compact aluminium and brass filters with fine mesh or sintered elements to trap debris before it reaches your carb, plus weighted clunks to maintain consistent pickup under hard driving. We stock popular sizes for standard silicone fuel line, with barbed fittings for secure, leak-free installs.

Browse trusted brands including Fastrax, HPI, Dubro and J Perkins, with serviceable designs you can unscrew and rinse, as well as low-restriction filters ideal for break‑in and high‑flow setups. Whether you’re refreshing a basher or building a race buggy, you’ll find the right filter, seals and spares here.

Fitting tips: mount the filter where you can access it easily, follow the flow arrow where shown, and check for air leaks after installation. Periodically clean the element with fresh fuel or after‑run oil to keep performance sharp.
