The Wacker Neuson 4238-140-0611 Fuel Tank Cap is a genuine OEM component designed for the BFS 2020AS floor saw. Sourced directly from Wacker Neuson, this cap is an exact match to the original part installed at the factory — ensuring correct fitment and a secure seal on the fuel tank. As a genuine OEM replacement, part 4238-140-0611 meets the same specifications as the part it replaces, so you can install with confidence. If you're servicing or restoring a BFS 2020AS, this is the correct cap to bring the machine back to proper operating condition.
Key Features
- Genuine OEM Seal Integrity — Engineered to the same sealing specification as the original, preventing fuel vapor escape and contamination ingress at the tank opening.
- Direct Tank Thread Match — Designed to thread directly onto the BFS 2020AS fuel tank filler neck with no modification — seats and seals just like the factory-installed cap.
- BFS 2020AS Compatibility — Verified fitment for the Wacker Neuson BFS 2020AS floor saw, eliminating guesswork when ordering a replacement.
- Fuel System Protection — A properly sealing tank cap keeps debris, water, and contaminants out of the fuel supply, protecting the engine and fuel system components from premature wear.
- Fuel Containment Safety — A secure, correctly fitting cap prevents fuel spillage during transport and operation — an important consideration on any saw operating around cutting slurry and wet conditions.
The fuel tank cap seals the filler opening on the machine's fuel tank, keeping fuel contained and the tank protected from outside contamination. A worn, cracked, or missing cap can allow dirt and moisture into the fuel system, leading to carburetor fouling, fuel delivery issues, and potential engine damage over time. On a floor saw like the BFS 2020AS — which operates in wet, slurry-heavy conditions — a properly sealing cap also prevents water intrusion that could compromise fuel quality and engine performance.
