Important Buyer Notes

• Technical Spec Code Match: Kohler engines utilize multiple styles of vacuum pulse and mechanical fuel pumps depending on the exact manufacturing year and application suffix. Please strictly verify your complete engine model and specification number against our list to ensure correct structural port alignment.

• Clean System Environment: Before installing the new kit components, verify that the crankcase vacuum pulse hole is clean and unobstructed by engine oil buildup, and replace old fuel lines to protect the fresh pump from rubber deterioration debris.

• Professional Assembly Advised: Dealing with highly combustible fuel systems requires proper safety protocols. Professional installation by an authorized small engine outdoor power technician is highly recommended.
