Restore Reliable Fuel Flow
Eliminate fueling inconsistencies and hard-starting issues with the Universal Parts Vacuum Operated Fuel Pump. Engineered for 50cc to 150cc 4-stroke and 2-stroke street scooters, this pump utilizes engine vacuum pulses to deliver a steady, pressurized flow of gasoline to your carburetor. Whether your factory pump has a torn internal diaphragm or you're upgrading a custom build, this robust cast-body unit provides the mechanical reliability needed for consistent throttle response.
Key Features
- Efficient Vacuum Pulse Operation: High-sensitivity internal diaphragm responds to even low-vacuum signals, ensuring reliable fuel delivery at idle and wide-open throttle.
- Durable Cast-Aluminium Housing: Built to withstand engine bay heat and vibration — superior longevity vs. plastic-housed alternatives.
- Clear Fitting Identification: Includes a brass "Gas In" fitting, barbed "Gas Out" cast fitting, and smooth vacuum line connection for intuitive, error-free installation.
- Standard 76mm Bolt Spacing: Industry-standard mounting footprint — direct bolt-on replacement for a wide range of scooter brands.

Mechanic's Note
If your scooter runs for a few minutes and then dies, or won't start after sitting, your fuel pump diaphragm may be compromised. When installing, always inspect your vacuum lines for cracks or dry rot — even a tiny air leak will prevent this pump from drawing fuel from the tank.
