Pro Chaser Kohler CV491S Fuel Pump Replacement Kit — Direct-Fit for CV490/492/493, Includes Inline Fuel Filter, Restores Reliable

The Pro Chaser CV491S fuel pump is a direct-fit replacement kit engineered to restore reliable fuel delivery for Kohler CV490, CV491S, CV492, CV492S, CV493 and CV493T engines.

If your small engine is showing signs of poor performance after sitting or following fuel contamination, a worn or clogged mechanical fuel pump is a common culprit. This kit ships with the pump assembly plus a fuel filter and is designed to match the mounting and vacuum/pressure characteristics used on the specified Kohler CV-series engines. Before ordering, compare your carburetor and pump location to the photos and, if unsure, send clear pictures from each side so we can confirm compatibility.

How will this pump affect engine starting and throttle response?

Replacing a failing fuel pump restores steady gasoline flow to the carburetor, which improves cold starts, idling stability and throttle transitions. A fresh filter included in the kit helps prevent debris from restricting flow, so acceleration stays consistent under load.

• Re-establishes proper fuel pressure and suction characteristics
• Reduces hesitation and sputter during acceleration
• Improves cold-start reliability when vapor lock or starvation occurs
• Includes an inline fuel filter to trap contaminants

Will this pump fit my Kohler CV490 / CV492 / CV493 engine?

The kit is intended for the Kohler models listed in the title, but small carburetor or housing variations may exist between production batches. Always compare the pump shape, mounting holes and fuel port orientations with your current part photos to ensure a match before installation.

• Designed for Kohler CV490, CV491S, CV492, CV492S, CV493, CV493T engines
• Check mounting pattern and port locations against your unit
• Contact seller with clear side-by-side photos for fit verification

What comes in the Pro Chaser fuel pump kit and what tools are needed?

This package includes one replacement mechanical fuel pump assembly and one inline fuel filter to help protect the carburetor. Basic hand tools suffice for installation—typically a wrench or socket set, a screwdriver and pliers to remove fuel lines and secure fittings.

• 1 x mechanical fuel pump assembly compatible with listed Kohler engines
• 1 x inline fuel filter for immediate filtration protection
• Simple hand tools required; no specialized equipment
• Recommended: clean rags and a small container for trapped fuel

How do I diagnose whether the pump is the problem?

Common signs include long cranking times, engine stalling under load, fuel odors near the engine, or visible fuel leaks at the pump. A basic test is to remove the outlet line and crank the engine briefly—consistent fuel delivery indicates the pump is functioning, while little or no flow suggests replacement is needed.

• Symptoms: hard starting, misfire, stalling, fuel leakage
• Quick flow test: check for fuel at the pump outlet while cranking
• Inspect the included filter for clogging as a possible cause
