The Mikuni pump operates using crankcase pressure pulses — no external power source required. A failing fuel pump is a common cause of fuel starvation, lean-running, and power drop-off under sustained full throttle, particularly in high-speed sections where fuel demand is greatest.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eSenior MAX EVO, Junior MAX EVO, Mini MAX EVO, and Micro MAX EVO\u003c\/strong\u003e. The pump is mounted to the carb bracket assembly and connects to the crankcase impulse port via a hose. Use the Mikuni Fuel Pump Gasket Set (R.296165) when installing.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.994483\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Mikuni pulse-operated diaphragm pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBefore replacing the fuel pump, check the impulse line and fuel filter (R.274161) first — a blocked line or filter is often the real cause of fuel starvation.
