The Honda 16700-ZA0-971 Fuel Pump Assembly (Electromagnetic) is a genuine OEM component designed for GX240, GX630, GX660, and GX690 horizontal shaft engines. As a direct OEM replacement, this fuel pump assembly is manufactured to Honda's original specifications, ensuring it operates exactly as the original unit did when your engine left the factory. Confirm your engine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at specific serial breaks within a model run.
Key Features
- Correct Fuel Delivery — Genuine OEM construction means this pump delivers the precise fuel volume and pressure the GX240, GX630, GX660, and GX690 engines require for consistent combustion and stable throttle response.
- Electromagnetic Design — The electromagnetic actuator mechanism drives the diaphragm without a mechanical linkage to the engine, making this a direct drop-in that reconnects to the existing wiring harness and fuel lines.
- Honda OEM Part — Sourced directly from Honda, part number 16700-ZA0-971 carries full OEM provenance — no substitutions, no reverse-engineered components.
- Serial Number Matters — Honda updates parts across production runs; check the serial number on your engine against the compatibility table to confirm this assembly is the correct revision for your unit.
- Restored Engine Performance — A failing fuel pump starves the engine of fuel, causing hard starting, erratic running, and power loss under load; replacing it with this assembly restores steady fuel delivery and full power output.
The fuel pump assembly draws fuel from the tank and delivers it at the correct pressure to the carburetor, where it is metered and mixed with air before combustion. On Honda horizontal shaft engines that position the tank at or below carburetor level, an electromagnetic pump is essential — gravity alone cannot supply adequate fuel flow under all operating conditions. When this pump weakens or fails, symptoms typically include lean-running, surging, hard cold starts, or the engine cutting out under load; replacing the assembly restores the reliable fuel supply the engine needs to run at full output.
