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. Sourced directly from Wacker Neuson, this hose is manufactured to the exact inner and outer diameter specifications required for a secure, leak-free connection in the fuel system. Compatible across multiple PT6Y and PT6YT configurations including AU and IN variants, part number is the correct replacement when your original hose shows signs of cracking, swelling, or fuel seepage. Keeping the fuel delivery path intact is essential to consistent engine starting and steady pump output on the job.
Key Features
- Exact Diameter Match: — Sized to 7.9 mm I.D. and 14.7 mm O.D. for a snug, interference-fit connection that seats correctly on OEM fuel fittings without trimming or adapting.
- Fuel-Grade Hose Construction: — Made from materials rated for continuous contact with gasoline, resisting softening, swelling, and degradation that cause leaks in lesser hoses.
- Genuine OEM Part: — Supplied by Wacker Neuson as part number 5100064423, ensuring it meets the same dimensional and material standards as the hose that came on your machine.
- Broad PT6Y Series Coverage: — Fits PT6Y, PT6YT, PT6Y-AU, PT6YT-IN, and PT6Y EPA T4 pump models, making it the go-to replacement across the PT6Y platform.
- Fuel System Safety: — A compromised fuel hose introduces fire and vapor hazards on the worksite; replacing it with the correct OEM specification hose restores safe, sealed fuel delivery.
A fuel hose carries gasoline from the tank to the carburetor or fuel inlet, maintaining a continuous, sealed flow that allows the engine to start reliably and run at a steady speed. When the hose cracks, hardens with age, or develops a loose fit at the barbed fittings, fuel can leak or air can enter the line — both conditions cause hard starting, rough running, or a complete loss of power to the pump. Replacing a worn hose promptly with the correct diameter part restores a fully sealed fuel path and eliminates the risk of fuel coming into contact with hot engine surfaces.
