The Wacker Neuson 4223-400-1303 Fuel Hose is a genuine OEM component designed for the G50 and G70 series portable generators. As a direct OEM replacement, this fuel hose is manufactured to the exact specifications of the original part, ensuring a proper fit across the wide range of G50 and G70 configurations — including Standard, Cold Weather, Custom, Extended Run, URI HVAC, and 600V variants spanning Tier 3, Tier 4i, and Tier 4 Final emissions levels. Sourced directly from Wacker Neuson, part number 4223-400-1303 delivers the confidence of a factory-matched component for a critical fuel system connection. Keep your generator running at full capacity with the correct OEM hose installed.
Key Features
- OEM-Matched Fuel Compatibility — Manufactured from fuel-resistant materials that meet the original material specification, preventing softening, cracking, or fuel seepage under continuous generator operation.
- Correct Diameter and End Fitment — Matches the original hose routing, diameter, and connection points on G50 and G70 generator fuel systems, allowing straightforward installation without modification to fittings or lines.
- Broad G50 and G70 Coverage — Fits an extensive range of G50 and G70 configurations including Standard, Cold Weather, Custom, Extended Run, URI HVAC, and 600V models across Tier 3, T4i, and T4F platforms.
- Sustained Fuel Delivery — A correctly seated fuel hose maintains consistent fuel flow to the engine, supporting stable generator output and preventing power interruptions caused by fuel starvation or leaks.
- Fuel System Safety — A cracked or deteriorating fuel hose creates a fire and leak hazard in an enclosed generator enclosure. Replacing with a genuine OEM hose restores the integrity of the fuel circuit and eliminates that risk.
The fuel hose carries diesel fuel from the tank or fuel supply connection through to the engine's fuel system on Wacker Neuson G50 and G70 generators. It must maintain a sealed, flexible connection under vibration, temperature cycling, and continuous fuel exposure — conditions that gradually degrade hose material over time. When a fuel hose cracks, softens, or develops a leak, the result can range from reduced engine performance due to air ingestion or fuel starvation, to a serious fuel leak within the generator enclosure. Routine inspection and timely replacement with part number 4223-400-1303 keeps the fuel circuit sealed and the generator performing as intended.
