LEIMO KPARTS Fuel Pump for Kohler K-Series 47-559-11-S — 10–16 HP direct-replacement, high-flow, ethanol-ready

LEIMO KPARTS 47-559-11-S is a direct-replacement mechanical fuel pump designed for Kohler K-Series and Magnum small engines, matching John Deere AM134269 and Gravely 38789 fitments.

This compact, high-flow fuel pump is built for 10–16 HP Kohler engines and compatible Magnum/Gravely/John Deere applications. It swaps into the same mounting pattern as the OEM part and is engineered to handle ethanol-blended fuels and routine operating demands. The unit measures 64 × 62 × 55 mm and uses a 39 mm hole spacing with 6.7 mm bolt holes for straightforward installation on matched engines.

How reliable and durable is this replacement pump?

Manufactured for durability, the pump uses robust internal components and a high-flow design to resist damage from modern fuels. It’s not the least expensive option available because materials and flow capacity are designed to outlast lower-grade alternatives.

• High-flow internals suited for ethanol blends and routine duty cycles
• Sturdy housing and reinforced mounting flange to reduce leak points
• Quality control aimed at consistent pumping performance across units

What are the key dimensions and installation details?

The pump’s overall size is compact: 64 mm long, 62 mm wide and 55 mm thick. Mounting hole centers are 39 mm apart with 6.7 mm diameter holes; these specs help confirm compatibility before purchase. While the pump is designed for DIY swap-outs, professional installation is recommended if you’re not experienced with small-engine fuel systems.

• Overall dimensions: 64 × 62 × 55 mm (L × W × T)
• Mounting hole center: 39 mm; hole diameter: 6.7 mm
• Designed to match OEM bolt pattern for direct replacement on listed engines

What should I expect during installation and maintenance?

Installation typically involves removing the old pump, transferring any linkages or gaskets, and bolting the new pump in place using the same fasteners. Replace any worn gaskets and inspect fuel lines for cracks or hardening; a clean install reduces future fuel-system issues.

• Pre-install: drain fuel and relieve system pressure for safety
• Use a new gasket or sealant where the pump meets the engine block
• Inspect fuel lines and clamps; replace if brittle or damaged
