VACUUM ( PULSE ) FUEL PUMPS

The Mikuni fuel pumps listed can be used on any 2-stroke or 4-stroke engine. The fuel pumps operate by using the fluctuating pressure on the intake side of both engines types.
Please note that when installing a vacuum fuel pump to a gravity fed carburetor vehicle, smaller needle valves must be installed to withstand the higher pump pressure.
We stock most types and sizes of Mikuni needle valves.
