49019-0031 Fuel Filter for Kawasaki FR691V FR651V FR730V FS691V FS730V FS651V Fuel Filter Spark Plug for Toro Cub Cadet Husqvarna Zero Turn Mower

What It Is

This is a replacement fuel filter (OEM part 49019-0031) designed to trap debris and sediment before it reaches the carburetor on Kawasaki FR and FS series V-twin engines. It’s commonly used on Toro, Cub Cadet, and Husqvarna zero-turn mowers with these engines.

Fitment & Compatibility

Before buying, confirm your engine model is one of these: FR691V, FR651V, FR730V, FS691V, FS730V, FS651V. Check the existing filter’s part number—if it’s not 49019-0031, measure the hose barb diameter (typically 1/4″ or 5/16″) and overall length (approx. 2.5″). This filter is a direct OEM replacement for Kawasaki, not a universal fit. It will not work on Kohler or Briggs & Stratton engines without adapter hoses. Verify your mower’s model number (e.g., Toro Z Master, Cub Cadet ZT1, Husqvarna Z254) to be sure, but the engine series is the key.

Key Things to Know

• Quality: Made by Kawasaki/Cub Cadet OEM supplier, so it matches factory specs. No cheap plastic or poor sealing.
• Installation: Easy—disconnect fuel line, swap filter, reattach. Use hose clamps or zip ties if original clamps are worn.
• Common gotcha: Fuel flow direction is marked with an arrow; install it pointing toward the carburetor. Reversing it can cause engine starvation.
• Frequency: Replace every 100 hours or annually, whichever comes first. A clogged filter causes hard starting and hesitation under load.

Should You Buy It

If you own a Kawasaki FR/FS-powered zero-turn and want a drop-in, no-guesswork filter that matches OEM specs, this is it. At $9.99 with a near-perfect rating, it’s a safe, low-cost maintenance item for anyone who values reliability over hunting for universal alternatives.
