The Wacker Neuson Fuel Hose 7.9 I.D. 14.7 O.D. is a genuine OEM component designed for PT6Y and PT6YT series trash pumps. Sourced directly from Wacker Neuson, this is the exact hose used in original production — same dimensions, same material grade, same fit. It is compatible across multiple PT6Y configurations including PT6Y-SA, PT6YT, PT6Y-AU, PT6YT-IN, and PT6Y EPA T4 models. When fuel system integrity matters, using the correct OEM part ensures the hose seats and seals exactly as engineered.
Key Features
- Correct Bore and Wall Dimensions — Specified at 7.9 mm internal diameter and 14.7 mm outer diameter, matching the original hose geometry for a secure, leak-free connection at both fittings.
- Genuine OEM Sourcing — Manufactured to Wacker Neuson's own fuel system material standards, ensuring compatibility with the fuel types and pressures used in PT6Y series pumps.
- Broad PT6Y Series Coverage — Fits PT6Y-SA, PT6YT, PT6Y-AU, PT6YT-IN, PT6Y EPA T4, and additional PT6Y variants, making it a practical stock item for fleets running multiple configurations.
- Fuel Delivery Integrity — A correctly sized hose maintains consistent fuel flow to the engine. A cracked, swollen, or undersized hose restricts flow, causes hard starting, and risks fuel leaks that can shut down operations.
- Fuel System Safety — Using a hose matched to the original I.D. and O.D. specification reduces the risk of loose connections or seepage at fuel line junctions — an important consideration on any engine-driven pump.
A fuel hose carries fuel from the tank to the engine's carburetor or fuel inlet, maintaining a steady and sealed flow throughout operation. The internal diameter controls fuel volume and flow rate, while the outer diameter and wall thickness determine how securely the hose clamps and seats on its barbed fittings. When a fuel hose degrades — through cracking, softening, or collapse — fuel delivery becomes inconsistent, leading to rough running, stalling, or visible leaks. Replacing a worn hose with the correct OEM part restores the sealed, properly flowing fuel circuit the engine depends on.
