The Honda 91424-Z4F-804 Fuel Tube (4.5X140) is a genuine OEM fuel tube designed for a wide range of Honda engines, generators, tillers, snow blowers, and water pumps including GX120, GX160, GX200, GX610, GX620, EG1400, EG2200, EG2500, HS724, FC600, FR600, FR800, WB20, WB30, WDP20, WDP30, WH15, WH20, WMP20, and WT20. As a direct Honda OEM component, this fuel tube is manufactured to the exact dimensions and material specifications Honda requires, ensuring a proper seal and consistent fuel delivery. The 4.5X140 designation identifies the specific inner diameter and length of this tube — matching these figures to your machine's service documentation is the key step before ordering. If your machine is listed in the fitment data, confirm your serial number against the compatibility table to make sure this is the correct tube for your specific production run.
Key Features
- Exact OEM Dimensions — the 4.5 mm inner diameter and 140 mm length are Honda's own specifications, ensuring the tube seats fully on fuel fittings without leaks or air ingestion
- Consistent Fuel Delivery — a correctly sized, undamaged fuel tube maintains steady fuel flow from tank to carburettor; a cracked or swollen tube starves the engine of fuel or causes hard starting and rough running
- Broad Cross-Equipment Fitment — listed for GX-series horizontal shaft engines, EG generators, HS724 two-stage snow blowers, FC600, FR600, and FR800 tillers, and multiple Honda water pump models including centrifugal and diaphragm variants
- Serial Number Verification Recommended — Honda supersedes fuel tube part numbers at production breaks, so check your machine's serial number against the fitment table to confirm part number 91424-Z4F-804 is correct for your unit
A fuel tube carries gasoline from the fuel tank to the carburettor, maintaining a sealed, unobstructed path that the engine depends on for every drop of fuel it consumes. Over time, fuel tubes degrade from heat cycling, ethanol-blended fuels, and age — cracking at the ends or softening and collapsing internally. When this happens, the engine may run lean, surge, or refuse to start. Replacing a deteriorated tube with the correct Honda OEM part restores the sealed fuel path and gets the machine running as intended.
