Pro Chaser CV491S Fuel Pump for Kohler CV490-CV493 Series — Direct-Replace with Inline Filter

Pro Chaser CV491S Fuel Pump Kit replaces the fuel pump on Kohler CV490/CV491S/CV492/CV492S/CV493/CV493T engines to restore steady fuel delivery and reliable engine run-up.

This fuel pump assembly is designed as a direct-replacement option for a range of Kohler small engines. It ships with the pump and an inline fuel filter to help keep contaminants from reaching the carburetor. Because Kohler carburetor variations exist, inspect compatibility carefully: compare images and mounting points with your current unit and contact us with photos if you need help confirming a match.

How will this pump affect my engine performance?

Installing a fresh fuel pump can eliminate fuel flow issues that cause hard starting, stalling, or inconsistent throttle response. The replacement restores expected fuel pressure and volume to the carburetor when the original pump is worn or leaking.

• Restores consistent fuel delivery for smoother starts and idle.
• Includes an inline fuel filter to reduce debris intake.
• Manufactured to fit Kohler CV49x/ CV493 series mounting and ports.

Will this kit fit my specific Kohler model and how do I confirm it?

Compatibility covers Kohler models CV490, CV491S, CV492, CV492S, CV493 and CV493T that use part number 12 559 02-S or an equivalent pump design. Minor carburetor differences may require visual confirmation before ordering.

• Compare the pump shape, bolt pattern, and fuel port locations to your existing pump.
• Check for the Kohler part number stamped on the old unit if available.
• Contact Pro Chaser with clear photos of both sides of your carburetor if uncertain.

What comes in the package and what tools will I need for installation?

The kit includes one replacement fuel pump and one inline fuel filter so you can swap components during a single service. Typical installation requires basic hand tools and minimal mechanical experience.

• Included: 1 x Pro Chaser fuel pump, 1 x inline fuel filter.
• Common tools: screwdriver set, socket or wrench to remove pump bolts, pliers for hose clamps.
• Allow time to drain fuel, replace hoses if brittle, and test for leaks after install.

How long should the replacement pump last and how can I extend its service life?

Longevity depends on fuel quality, operating conditions, and maintenance; using the included filter and avoiding contaminated fuel will help prolong pump life. Regular inspection and replacing the filter when dirty reduce wear and the chance of pump failure.

• Use clean, stabilized fuel and avoid water-contaminated gas.
• Replace the inline filter at regular service intervals or if clogged.
• Inspect fuel lines and clamps for leaks or deterioration during pump replacement.
