The Honda 17703-Z0H-J71 Fuel Tube A is a genuine OEM replacement designed for GX25 horizontal shaft engines, HHT25 and UMC425 trimmers, and the WX10 water pump. As a direct Honda OEM component, this fuel tube is manufactured to the exact dimensions and material specification Honda requires for consistent fuel delivery in these compact units. It is compatible with the GX25, HHT25, UMC425, and WX10 — confirm your model and serial number against the fitment table before ordering, as Honda supersedes parts at production breaks.
Key Features
- Genuine Honda OEM Construction — manufactured to Honda's exact specification for this fuel routing position, ensuring the correct diameter, length, and material grade for a leak-free connection in the fuel system of these small-displacement units
- Exact-Fit Replacement — engineered to replace the original Fuel Tube A in the GX25 engine, HHT25 and UMC425 trimmers, and the WX10 water pump without cutting or adapting the line
- Fuel System Integrity — a cracked, kinked, or hardened fuel tube disrupts fuel flow to the carburettor, causing hard starting, lean-running conditions, or stalling under load; replacing it with part number 17703-Z0H-J71 restores proper fuel delivery
- Verify Before Ordering — Honda updates parts at serial number breaks, so check your machine's serial number against the compatibility table to confirm this is the correct tube for your unit
The Fuel Tube A carries fuel from the tank to the carburettor in these compact Honda-powered units. In small-displacement engines and equipment like the GX25 engine, HHT25 and UMC425 trimmers, and the WX10 water pump, the fuel tube must maintain a flexible, airtight passage to keep fuel flowing steadily at the low volumes these carburettors require. Over time, the tube can harden, crack, or collapse from heat cycling and fuel exposure, restricting or cutting off fuel flow entirely — resulting in rough running, stalling, or failure to start. Replacing a worn tube promptly keeps the fuel system operating as designed.
