The Wacker Neuson Fuel Hose 7.9 I.D. 14.7 O.D. is a genuine OEM component designed for the PT6Y and PT6YT series trash pumps, including PT6Y-AU and PT6YT-IN variants. As a direct OEM replacement, part is manufactured to Wacker Neuson's exact dimensional and material specifications, ensuring a consistent, leak-free connection in the fuel delivery system. This hose fits across multiple PT6Y-series configurations, making it a reliable go-to when servicing or overhauling pumps in this family. Keep a spare on hand to get your pump back up and running without delay.
Key Features
- OEM-Spec Inner and Outer Diameter — Sized at 7.9 mm I.D. and 14.7 mm O.D. to match the original fuel line routing exactly, preventing seepage at connection points.
- Fuel-Resistant Hose Construction — Built from materials rated to handle gasoline and fuel blends, resisting swelling, cracking, and degradation over time.
- Drop-In Replacement — Routes and connects exactly like the original hose, allowing straightforward removal and reinstallation without reworking the fuel line path.
- Broad PT6Y-Series Coverage — Compatible with PT6Y, PT6YT, PT6Y-AU, PT6YT-IN, and PT6Y EPA T4 pump models, consolidating your parts sourcing across the series.
- Fuel System Integrity — A compromised fuel hose starves the engine of consistent fuel flow or allows dangerous leaks; replacing it promptly restores safe, steady engine operation.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so the dimensions, wall thickness, and material grade match what left the factory originally.
A fuel hose carries gasoline from the tank to the carburetor or fuel system components, maintaining a sealed, pressurized path that keeps the engine supplied with the right volume of fuel at all times. Over time, exposure to fuel, heat, and vibration causes the hose material to harden, crack, or swell at the fittings — leading to fuel starvation, hard starting, or fuel leaks that create a fire hazard. Replacing a worn hose with the correct OEM part restores a tight, reliable seal and keeps the pump running safely at full performance.
