Wacker Neuson 5000181596 Fuel Fill Hose

The Wacker Neuson Fuel Fill Hose is a genuine OEM component designed for HI-series indirect-fired air heaters, including the HI750, HI900, and HI260 model families. As a direct OEM replacement, this hose is produced to the same specifications as the original part fitted at the factory, ensuring a proper, leak-free connection in your heater's fuel system. It is confirmed to fit across a wide range of HI750 and HI900 configurations — including diesel, gasoline, and dual-fuel variants — as well as the HI260 oil-fired heater with tank. Keep a verified part number on hand: is the correct reference for all compatible configurations listed.

Key Features

• Genuine OEM Construction — Built to the same hose material grade, wall thickness, and end-fitting spec as the original, maintaining a secure, fuel-tight connection throughout the heater's operating temperature range.
• Drop-In Fitment — Matches the original routing path and connection points in the fuel fill circuit, so installation follows the same procedure as the part being replaced.
• Broad HI-Series Compatibility — Fits HI750 (diesel, gasoline, dual-fuel, and surge-brake variants), HI900 (diesel, DGM, and electric surge configurations), and HI260 oil-fired heaters with tank.
• Fuel System Integrity — A sound fuel fill hose maintains proper fuel flow to the burner assembly; a cracked or degraded hose can cause fuel leaks, erratic burner performance, or heater shutdown in cold-weather jobsite conditions.
• Fuel System Safety — On indirect-fired heaters operating in enclosed or semi-enclosed environments, a deteriorated fill hose poses a genuine fire and vapor hazard; replacing a worn hose promptly is a critical safety step.

The fuel fill hose is the flexible line that channels fuel from the external fill point into the heater's onboard fuel supply. On indirect-fired air heaters like the HI750 and HI900 series, this hose must maintain a continuous, sealed connection under the vibration and thermal cycling common to portable heating equipment. Over time, heat exposure, fuel contact, and flexing can cause the hose material to crack, stiffen, or leak at the fittings — symptoms that show up as fuel odor, visible seepage, or inconsistent burner ignition. Replacing the hose at the first sign of wear restores fuel system integrity and keeps the heater operating safely in demanding cold-weather applications.
