Wacker Neuson 5000216071 Float Needle Valve

The Wacker Neuson Float Needle Valve is a genuine OEM component designed for CRT48-35V series curbing and concrete paving machines, including the standard, EU, and Power Steer variants. As a factory-sourced part, it meets the exact tolerances required for proper carburetor fuel metering in these models. Confirm your machine's model number against the fitment list — the covers the CRT48-35V, CRT48-35V EU, and CRT48-35V-PS configurations. Keeping the correct valve in service ensures consistent fuel delivery and protects engine performance across the full range of CRT48-35V applications.

Key Features

• Exact Fuel Metering Tolerance — Manufactured to OEM specification, this float needle valve seats and seals with the precision that correct carburetor fuel metering demands — no compromise on needle tip geometry or seat contact.
• Direct Carburetor Fit — Drops directly into the carburetor float bowl assembly on compatible CRT48-35V machines, matching the original mounting dimensions and needle taper without modification.
• Broad CRT48-35V Series Coverage — Confirmed fitment across the CRT48-35V, CRT48-35V EU, and CRT48-35V Power Steer models, covering the full current production range of this concrete curber series.
• Fuel System Integrity — A worn or damaged float needle valve allows fuel to overflow into the float bowl, causing flooding, rough running, and hard starts. Replacing it restores clean shut-off and stable idle.
• Genuine OEM Sourcing — Supplied directly under the Wacker Neuson OEM part number 5000216071, so you receive the same component installed at the factory — not a dimensional approximation.
• Fuel System Safety — A correctly seating float needle valve prevents uncontrolled fuel flow, which is essential for safe carburetor operation and reducing the risk of flooding-related hazards on fuel-powered equipment.

The float needle valve is a small but critical component inside the carburetor's float chamber. It works together with the float to regulate how much fuel enters the bowl — when the float rises to the correct level, the needle valve closes off the fuel inlet to prevent overflow. If the needle tip wears, the seat becomes damaged, or the valve fails to seal fully, fuel floods the bowl, causing the engine to run rich, stall, or become difficult to start. Replacing a faulty float needle valve is one of the most direct ways to restore correct fuel metering and smooth engine operation.
