The Honda 17702-Z0H-821 Fuel Return Tube is a genuine OEM component designed for FG110 tillers and GX25 horizontal shaft engines. As a direct Honda OEM part, this tube is manufactured to the exact specifications Honda requires for proper fuel system function. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and fitment can vary across production runs.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this tube matches the original in material dimensions and routing geometry, ensuring a drop-in fit without modification
- Fuel System Integrity — a correctly functioning fuel return tube keeps excess fuel routed back to the tank at the right pressure, protecting the carburettor from flooding and supporting consistent engine operation
- Broad Compact-Engine Fitment — covers the FG110 tiller and GX25 horizontal shaft engine; verify your serial number against the compatibility table to confirm this is the correct tube for your unit
The fuel return tube carries surplus fuel from the carburettor back to the fuel tank, maintaining the correct fuel pressure and flow balance within the fuel system. Without a sound return tube, fuel pressure can build unevenly, leading to rich running conditions, hard starting, or fuel leaks. On small-displacement engines like the GX25 and on equipment like the FG110 tiller, keeping this line in good condition is essential to steady, fuel-efficient operation.
