The Wacker Neuson is a genuine OEM Fuel Hose, 31.5in designed for the G-Series portable generator lineup and LTW20Z light tower series. As a direct OEM replacement, this hose is manufactured to the exact length, inner diameter, and material specification required by the original fuel system design — ensuring a secure, leak-free connection right out of the box. Fitment spans a broad range of G-Series generators including the G25, G50, G70, G100, G120, G130, G150, G180, and G240 across multiple Tier configurations, as well as the LTW20Z1 and LTW20Z3 light towers. When your fuel delivery system needs attention, sourcing the correct OEM part number is the fastest way to restore full machine output.
Key Features
- OEM-Grade Fuel Compatibility — Constructed from fuel-resistant hose material rated for diesel fuel delivery, maintaining consistent flow and resisting degradation from prolonged fuel contact.
- Exact 31.5in Length — Cut to the precise 31.5-inch dimension specified for the original fuel routing path; installs cleanly between factory connection points without trimming or splicing.
- Wide G-Series and LTW20Z Fitment — Confirmed for G25 through G240 generators across Tier 3, T4i, T4F, and Cold Weather configurations, plus LTW20Z1 and LTW20Z3 light towers.
- Sustained Fuel Delivery Integrity — A correctly functioning fuel hose maintains steady, uninterrupted fuel supply to the engine; a cracked or aged hose can cause hard starts, rough running, or dangerous fuel leaks.
- Fuel System Safety — Using the correct OEM hose with verified material and pressure ratings minimizes the risk of fuel seepage around connections — a genuine safety consideration on diesel-powered equipment running in enclosed or temporary structures.
The fuel hose carries diesel fuel from the tank or fuel filter assembly to the engine's injection system, maintaining a steady, pressurized supply at the correct flow rate. At 31.5 inches, this hose spans the specific routing distance engineered into the G-Series generator and LTW20Z light tower platforms. Over time, fuel hoses can harden, crack, or develop pinhole leaks due to heat cycling, vibration, and prolonged fuel exposure — symptoms that show up as fuel odor, staining near connections, rough engine behavior, or an inability to maintain prime. Replacing a worn hose promptly with the correct OEM part keeps the fuel system sealed and the engine running at full rated output.
