Review on High-Quality Replacement Fuel Pump for Yamaha Zuma 125 2009-2015 | OE# S9-E3907-10-00 by Chad Young

I received this pump unexpectedly in less than 48 hours southwest of Oklahoma from Hayward, California. For that alone he deserves three and a half gold stars. Rather than spending $$$ on a complete fuel pump assembly, we offer an OEM fuel pump replacement. There is no video on youtube so I just started unscrewing the parts until I got to the fuel pump. The biggest challenge was getting the plastic case apart without breaking anything I could do. All plugged in and voila! This little motor sounds solid compared to the OEM pump. Unlike before, where it sometimes started on the second try, the engine started immediately after pumping. Took a test drive and all my expectations were met. When I got home, I noticed that even if I turned off the key, it temporarily reverted to fuel line pressure. Worth every penny and more instead of replacing the pump assembly.
