Wacker Neuson 5000173444 Carbon Canister and Hose Assembly

The Wacker Neuson is a genuine OEM Carbon Canister and Hose Assembly designed for the GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A series portable generators. As a factory-sourced component, it meets the exact emissions compliance specifications Wacker Neuson builds into these generators — including CAN GFI, CARB GFI, EPA, and CSA configurations. This assembly is the correct replacement for all standard, wheel kit, electric start, and premium variants across the GP and GPS generator families. Verifying your generator's model number against the fitment list confirms a direct, worry-free replacement installation.

Key Features

• Emissions-Grade Material Compliance — Built to the same vapor-capture specifications as the factory unit, maintaining proper fuel vapor flow through the canister and hose routing on your generator.
• Genuine OEM Sourcing — Sourced directly from Wacker Neuson, this part carries the same part number and construction as the component installed at the factory — no guesswork on fit or spec.
• Broad GP and GPS Generator Fitment — Covers GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A generators across standard, wheel kit, electric start, CAN GFI, CARB GFI, EPA, and CSA configurations.
• Fuel Vapor System Integrity — A worn or cracked canister or hose allows raw fuel vapors to escape rather than route correctly, which can trigger emissions failures and create unsafe operating conditions around the generator.
• Emissions System Safety — Proper canister and hose function is essential for regulatory compliance on CAN GFI, CARB GFI, and EPA-rated units; using the correct OEM assembly keeps your generator operating within its certified emissions standard.

The carbon canister is part of the generator's evaporative emissions control system. It captures fuel vapors from the fuel tank that would otherwise vent to the atmosphere, storing them in activated carbon until the engine purges them during normal operation. The hose assembly connects the canister to the fuel tank and engine intake, ensuring vapor flow follows the correct path. When the canister becomes saturated or the hose cracks or collapses, vapors can escape into the surrounding environment — creating compliance issues on regulated units and increasing the risk of fuel odor or ignition hazard near the machine.
