Key Features

• Low-Permeation Construction: — The hose wall material is rated for low fuel vapor permeation, helping the generator fuel system meet emissions standards and resist fuel degradation over time.
• Exact OEM Length and Diameter: — Cut to 25.75 inches at 3/16-inch inner diameter, this hose routes and connects the same way as the original, with no trimming or adapting needed.
• Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson, part number 5000165582 carries the same material spec and quality validation as the hose fitted at the factory.
• GP4000 Generator Fitment: — Confirmed fit across multiple GP4000 portable generator configurations, covering both standard and premium variants in the GP4000 lineup.
• Fuel System Integrity: — A cracked, hardened, or deteriorated fuel hose causes fuel leaks, rough running, and potential fire risk. Replacing with the correct OEM hose restores safe, consistent fuel flow to the engine.
• Fuel System Safety: — Fuel hoses are a safety-critical component. Using the specified low-perm OEM hose ensures the connection points seal correctly and the material holds up to continuous fuel contact without softening or cracking.

The fuel hose carries gasoline from the tank to the carburetor or fuel inlet, maintaining a sealed, steady supply of fuel to keep the engine running at the correct mixture. In a portable generator like the GP4000, a properly functioning fuel hose is essential for consistent power output and reliable starts. When a fuel hose ages, it can harden, crack, or develop pinhole leaks that starve the engine of fuel, cause rough operation, or create a fire hazard — making timely replacement with the correct OEM part a straightforward but important service step.
