The Honda 91424-Z4M-023 Fuel Tube (4.5X145) is a genuine OEM replacement designed for a wide range of Honda engines and power equipment, including GX160 and GX200 horizontal shaft engines, WT30 and WB20 water pumps, HS724 and HSS724 two-stage snow blowers, WH15, WH20, WMP20, WT20, WB30 water pumps, and the FC600 tiller. As a direct Honda OEM component, this fuel tube is manufactured to the exact dimensions and material specification Honda requires for reliable fuel delivery. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes parts across production runs and the correct tube for your unit depends on the build date.
Key Features
- Correct Fuel Line Dimensions — the 4.5 mm inner diameter and 145 mm length are the exact measurements Honda specifies for this application, ensuring a leak-free connection between fuel system components without trimming or adapting
- Genuine OEM Construction — sourced directly from Honda, this tube is made to the same material standard as the original, resisting fuel permeation and maintaining flexibility across the operating temperature range of the equipment it serves
- Broad Fitment Across Honda Equipment Lines — listed for GX160 and GX200 horizontal shaft engines, WT20, WT30, WB20, WB30, WH15, WH20, and WMP20 water pumps, HS724 and HSS724 two-stage snow blowers, and the FC600 tiller
- Serial Number Verification Recommended — Honda updates fuel system parts at production serial breaks; check your unit's serial number against the compatibility table to confirm this is the right tube for your specific build
- Restored Fuel Flow — a cracked, hardened, or collapsed fuel tube restricts or cuts off fuel delivery, causing hard starting and rough running; replacing it with the correct OEM tube restores consistent fuel flow to the carburetor
The fuel tube carries fuel from the tank to the carburetor, maintaining a steady, unobstructed flow that the engine or equipment needs to start and run correctly. Over time, the tube can harden, crack, or collapse from heat cycling and prolonged exposure to fuel, which interrupts delivery and causes lean-running conditions, hesitation, or a no-start situation. Replacing a degraded tube with a correctly sized OEM part restores the integrity of the fuel path and is one of the most straightforward steps in a routine fuel system service.
