Product Overview
The pump uses engine pulse/vacuum rather than an electrical motor to move fuel from the tank toward the carburetor. A weak diaphragm can show up as hard starting, fuel starvation under load, intermittent stalling or an engine that runs better only after the fuel system is manually primed.
Kawasaki parts information lists 49040-2067 as the fuel pump on the Mule 500 KAF300A, and the same pump is widely cross-listed for Mule 520 and 550 KAF300 applications. Hose routing and condition should be checked during installation because cracked pulse or fuel lines can mimic a failed pump.
Key Features & Performance
- Vacuum/pulse-operated design—no electrical hookup required
- Restores fuel delivery to the carburetor when the original diaphragm pump weakens

Frequently Asked Questions
Q: Does this pump use 12-volt power?
A: No. This style of Mule fuel pump is driven by engine pulse/vacuum.
Q: What else should I inspect if the Mule still starves for fuel?
A: Check the pulse hose, fuel lines, filter, tank vent and carburetor inlet before assuming the new pump is the only cause.
Confirm the original pump number and KAF300 model designation before purchase.
