The Wacker Neuson 5100027051 is a genuine OEM Hose designed for the Wacker Neuson G-series portable generator lineup, including G25, G50, G70, G100, G130, and G150 models across Standard, Cold Weather, Extended Run, Custom, Mobile, and Battlefield Tier 4 configurations. As a direct OEM replacement, the 5100027051 is manufactured to the same specifications as the original part that shipped with your machine, ensuring correct routing, connection, and sealing without guesswork. This Hose fits an extensive range of G-series variants — from the compact G25 through to the high-output G150 — covering virtually every configuration Wacker Neuson has offered in the Tier 4 Final and Tier 4i generator families. If your generator's original hose is cracked, leaking, or deteriorating, replacing it promptly with the correct OEM part keeps fluid or air circuits operating as intended and protects surrounding components from damage.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specification, ensuring the hose maintains proper pressure rating, flexibility, and resistance to the operating temperatures found inside Wacker Neuson G-series generators.
- Correct Routing and Connection Geometry — Matches the original hose profile exactly, so it seats flush at both connection points without stretching, kinking, or adapter hardware.
- Broad G-Series Compatibility — A single part number covers G25, G50, G70, G100, G130, and G150 generator configurations, including Standard, Cold Weather, Extended Run, Custom, Mobile, and 600V Tier 4 Final variants.
- Protects Circuit Integrity — A worn or cracked hose allows fluid or air loss that can starve downstream systems, cause overheating, or trigger shutdowns; replacing with part 5100027051 restores full circuit function.
- Fuel and Fluid System Safety — On generator applications where hoses carry fuel or coolant, an intact, properly rated OEM hose is essential to prevent leaks that create fire or contamination hazards on the jobsite.
A hose in a portable generator serves as a conduit for moving fluids or air between system components — whether that is coolant circulating through the engine's thermal management circuit, fuel traveling from the tank to the engine, or air routed through an induction or emissions system. When a hose degrades, cracks, or loses its seal at either end, the affected circuit loses pressure or volume, which can lead to overheating, fuel starvation, or increased emissions. Replacing a failed hose promptly with the correct OEM part restores the circuit to its designed operating condition and prevents secondary damage to pumps, coolers, or engine components downstream.
