Wacker Neuson 1000464344 Reflux Line 3tnv80ft

The Wacker Neuson is a genuine OEM Reflux Line 3tnv80ft designed for PT6Y and PT6YT series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this part carries the same specification as the original component installed at the factory, ensuring a correct, confidence-inspiring replacement. Verified fitment spans multiple PT6Y configurations including PT6Y-SA, PT6YT, PT6Y-AU, PT6YT-IN, and PT6Y EPA T4 variants.

Key Features

• Genuine OEM Fluid Line Integrity — Manufactured to the exact pressure and material tolerances required for the 3tnv80ft engine's reflux circuit, ensuring the line seats and seals correctly at both connection points.
• Direct-Fit Replacement — Engineered to match the original routing, end fittings, and length of the factory line, allowing straightforward installation without reworking adjacent components.
• Broad PT6Y Series Coverage — Confirmed fitment across PT6Y-SA, PT6Y-AU, PT6YT, PT6YT-IN, and PT6Y EPA T4 models, making part number 1000464344 the correct choice across the PT6Y pump family.
• Sustained Engine Cooling and Fuel System Stability — A properly functioning reflux line maintains correct fluid return flow within the engine circuit; a cracked, blocked, or degraded line can cause overheating or irregular engine behavior that interrupts pump output.
• Fuel System Safety Compliance — As a component within the engine's fluid circuit, using a genuine OEM line ensures the connection geometry and material ratings meet the original design intent, reducing the risk of leaks in a high-cycle pumping environment.

The reflux line routes returning fluid — typically coolant or fuel return — back through the engine's circulation circuit on the 3tnv80ft-powered PT6Y trash pump. It acts as a controlled return path that keeps fluid temperatures and pressures balanced during sustained pump operation. When this line cracks, hardens with age, or develops a leak at either fitting, fluid loss or pressure imbalance can cause the engine to run hot, lose efficiency, or shut down under load.
