Honda 95005-45001-50M Vacuum Bulk Hose (4.5X1000)

The Honda 95005-45001-50M Vacuum Bulk Hose (4.5X1000) is a genuine OEM replacement designed for BF25, BF30, BF40, and BF50 outboard motors, as well as GCV190 vertical shaft engines. As a bulk-format hose, this component is sold by length, giving technicians the flexibility to cut it to the exact measurement their application requires. Sourcing genuine Honda vacuum hose ensures the correct 4.5 mm inside diameter and wall specification that Honda's fuel and vacuum routing demands. Confirm your machine's serial number against the fitment table before ordering to ensure this is the correct hose for your specific unit.

Key Features

• Genuine OEM Honda Hose — manufactured to Honda's exact 4.5 mm bore dimension, maintaining the vacuum integrity that fuel system and emissions routing depends on in BF-series outboards and GCV190 engines
• Bulk Length Format — supplied as a 1000 mm length, allowing technicians to cut the hose to the precise measurement needed rather than working around a pre-cut piece
• Broad Fitment — listed for BF25, BF30, BF40, and BF50 outboard motors and the GCV190 vertical shaft engine; verify your serial number against the fitment table to confirm applicability to your unit
• System Integrity — a cracked or hardened vacuum hose causes lean running, rough idle, and unreliable throttle response; replacing it with a correctly sized OEM hose restores consistent vacuum signals throughout the system

A vacuum hose routes low-pressure vacuum signals between components such as the fuel cock, carburettor, and any vacuum-operated valves or emissions ports in the engine or outboard powerhead. When this hose cracks, collapses, or hardens with age, the vacuum signal is lost or diluted, causing the engine or outboard to run erratically, idle roughly, or fail to draw fuel properly. Replacing a degraded hose with a correctly dimensioned OEM piece restores the sealed, consistent signal those components rely on to operate as designed.
