Mikuni DF44-227 Vacuum Diaphragm Fuel Pump | Universal Fit
Description
The Mikuni DF44-227 is the benchmark vacuum-actuated fuel pump for small-displacement carbureted vehicles. Made in Japan, this rectangular-body pump reliably moves fuel from tank to engine on everything from GY6 and QMB139 scooters to minibikes, go-karts, and even marine applications with 1/4" fuel lines. Ideal for builds where the fuel tank sits at or below engine height — including popular platforms like the Icebear Maddog and Honda Ruckus.
