The MIKUNI Carburetor/Fuel Pump Rebuild Kit provides the essential components required to restore the performance of BN34, BN38, BN44, and BN46 square and round pump watercraft carburetors. Each kit contains all necessary diaphragms, gaskets, and hardware to facilitate a complete disassembly and rebuild process. Because the available kits are categorized by specific carburetor model size, it is critical to verify the exact model designation of your unit prior to purchase to ensure proper fitment.
These rebuild kits are sold on a per-carburetor basis, allowing for precise inventory management for single-unit or multi-unit service projects. While the kit includes the core sealing and structural elements needed for the rebuild, needle and seat components are not included and must be sourced separately. This configuration ensures that technicians can address the most common wear items in the fuel pump assembly while maintaining the option to replace precision metering components as required by the specific condition of the carburetor.
