Kohler Valve-Cover Fuel Pump Kit 24 559 10-S — OEM replacement kit with gaskets & mounting hardware

Genuine KOHLER valve-cover fuel pump kit 24 559 10-S is a factory replacement assembly designed to restore proper fuel delivery and seal integrity on compatible Kohler engines.

This OEM kit includes the parts Kohler specifies to replace worn or damaged valve-cover-mounted fuel pump components. It supersedes older part numbers (24-559-08-S, 24-393-22-S, 24-393-19-S), making it the direct-fit option when you're servicing small engines that use Kohler’s valve cover fuel pump design. Using the correct factory kit helps preserve engine performance, avoids compatibility guesswork, and matches the materials and tolerances Kohler engineered for the system.

How do I know if this kit fits my engine?

Check the engine’s service manual or the existing part number stamped on the valve cover or fuel pump assembly. The 24 559 10-S replaces several prior MPNs, but compatibility depends on the exact engine family and model year.

• Compare the OEM part numbers printed on your current component to 24 559 10-S and the prior numbers listed.
• Consult your Kohler engine owner or service manual for valve-cover pump parts lists.
• If in doubt, provide engine model and serial number to a Kohler dealer for confirmation.

What does the kit contain and what should I inspect during replacement?

The kit supplies the factory valve cover and pump hardware required for a proper swap, including gaskets and mounting components. During replacement, inspect mating surfaces, fuel lines, and nearby seals for wear or contamination to avoid repeated service.

• Verify included gaskets are intact and match the valve cover shape before installation.
• Look for cracked or hardened fuel lines; replace lines or clamps if necessary.
• Clean the valve cover and surrounding area to prevent debris from entering the fuel system.

How difficult is installation and what tools are recommended?

Installation is typically straightforward for anyone comfortable with basic engine maintenance. You’ll need common hand tools and should follow torque specifications and seal-preparation steps laid out in Kohler service documentation.

• Basic tools: socket set, torque wrench, screwdrivers, and pliers for clamps.
• Use a torque wrench to avoid under- or over-tightening fasteners on the valve cover.
• Keep a clean workspace and fresh fuel-safe rags to protect the pump and gaskets while fitting.

Why choose an OEM Kohler kit instead of aftermarket parts?

OEM Kohler kits are manufactured to the original specifications and materials, ensuring fit, function, and longevity comparable to the parts shipped with the engine. That consistency reduces installation surprises and helps maintain warranty and service records where applicable.

• Direct-fit form, fit, and function with fewer modification needs.
• Materials and manufacturing tolerances match Kohler’s original design.
• Simplifies parts lookup with clear OEM numbering and dealer support.
