FAQ

This pump is compatible with Kawasaki FS, FR, FX, and FT series engines, including models FS481V, FS541V, FS600V, FS651V, FS691V, FS730V, FR541V, FR600V, FR651V, FR691V, and FR730V. It is widely used on John Deere equipment such as the 636M, 647A, 657A, 667A, 652B, 648M, 652M, 648R, Z910A, Z920A, Z920M, Z920R, and various walk-behind units like the WG and WH series.
This unit replaces Kawasaki OEM part numbers 49040-7008 and 49040-0770. It is also a direct replacement for John Deere part numbers MIU12470 and UC16533. It also cross-references with Stens part number 520-444.
If your engine is struggling to start, surging during operation, or losing power under load, the fuel pump may be failing to deliver consistent pressure. You may also notice the engine stalling shortly after starting or failing to run at high RPMs. If you smell raw fuel or notice the engine oil level rising (indicating fuel is leaking into the crankcase), the pump's internal diaphragm has likely ruptured.
Yes. Pay close attention to the orientation of the inlet and outlet ports to ensure they match your original configuration. When testing the pump for the first time after installation, you can briefly disconnect the outlet hose for 2–3 seconds to verify that fuel is being pumped correctly before reconnecting it to the carburetor.
It is highly recommended to replace your fuel filter and inspect all fuel lines for signs of cracking or hardening. If your fuel lines are brittle, they will not seal properly on the new pump's nipples, which can lead to air leaks and poor performance. Always ensure you are using fresh fuel, as this pump is not designed for use with fuel containing more than 10% ethanol.
