What It Is

This is a complete replacement fuel pump kit for Kawasaki FR and FS series V-twin engines (18–24 HP), commonly found on zero-turn mowers, lawn tractors, and commercial walk-behinds. It includes the pump, fuel filter, and clamps—everything needed to restore fuel delivery when the original pump fails or becomes erratic.

Fitment & Compatibility

• Engine models: FR541V, FR600V, FR651V, FR691V, FR730V, FS481V, FS541V, FS600V, FS651V, FS691V, FS730V (18HP, 21.5HP, 22HP, 23HP, 24HP).
• Machine brands: Gravely, John Deere, Cub Cadet, Toro, Exmark, Husqvarna, Bad Boy, Ferris, and others using these Kawasaki engines.
• OEM replacement: Direct fit for Kawasaki part numbers 49040-7007, 49040-7011, and 49040-7014.
• Check before buying: Verify your engine model number (stamped on the valve cover or blower housing). Measure the fuel line diameter—most use 5/16" (8mm) hose, but confirm yours matches the included clamps. This pump is a vacuum-operated pulse type; it will not work on gravity-feed or electric-pump systems.

Key Things to Know

• Quality: This is an aftermarket pump, not OEM Kawasaki. Most users report it works well, but a few note slightly thinner plastic or less durable pulse port nipples. Inspect the pulse port carefully for cracks before installation.
• Installation difficulty: Easy—takes about 15–30 minutes. You’ll need a screwdriver and possibly pliers. Disconnect the battery first, and label the fuel and pulse lines to avoid mixing them up.
• Common gotcha: The pump pulses from crankcase pressure. If your engine has a blocked pulse port or a worn-out crankcase breather, the pump may not work. Also, replace the fuel filter included in the kit; the OEM filter is often better quality.
• Fuel line compatibility: The included clamps may be too small for some aftermarket hoses. Have a few extra clamps on hand (5/16" or 3/8" as needed).

Should You Buy It

If your Kawasaki FR/FS engine is losing prime, surging, or not getting fuel, and you want a budget-friendly fix that includes all necessary parts, this kit is a solid choice. It’s not OEM, but for $14.99 it’s worth trying before spending $40+ on a genuine Kawasaki pump. Just be prepared to replace the included filter with a better one if you’re running a commercial mower hard.
