2-Pack 691035 Fuel Filter Replacement for Cub Cadet RZT22 (17AA5A7P710, 17AA5A7P712) Zero-Turn Riding Lawn Mower - Compatible with 493629 Fuel Filter 40 Micron

What It Is

This is a 2-pack of 40-micron fuel filters designed for small engines on Cub Cadet zero-turn mowers, specifically the RZT22 models. It filters debris from gasoline before it reaches the carburetor, preventing clogs and engine performance issues.

Fitment & Compatibility

• Direct replacement for OEM part 691035 and cross-compatible with 493629.
• Confirmed fit: Cub Cadet RZT22 models with serial numbers 17AA5A7P710 and 17AA5A7P712.
• Measurement check: Filter is roughly 1.5" long with 1/4" barbed inlet/outlet. Measure your old filter’s length and barb diameter—if they match, it fits.
• Not universal: Will not fit mowers with larger fuel lines (e.g., 5/16" or 3/8" barbs). Verify your fuel line inner diameter is 1/4" before buying.
• Aftermarket note: This is not a Cub Cadet OEM part, but it meets the same micron rating and dimensions.

Key Things to Know

• Installation difficulty: Very easy—pull off old hose clamps, swap the filter, and re-clamp. No tools beyond pliers needed.
• Flow direction: Arrow on the filter body must point toward the carburetor (fuel pump to carb). Reversing it can restrict flow.
• 40-micron rating: Standard for most small engines. Good balance of filtration vs. flow—won’t starve the engine unless fuel is heavily contaminated.
• Common gotcha: Old hose may be brittle; if it cracks when you remove the filter, replace the hose (usually 1/4" ID fuel line, sold separately).

Should You Buy It

If you own a Cub Cadet RZT22 with the listed serial numbers and need a budget-friendly, drop-in fuel filter replacement, this 2-pack is a solid choice. It’s cheap, easy to install, and matches OEM specs. Avoid if your mower uses larger fuel lines or if you prefer genuine Cub Cadet parts.
