Vacuum Fuel Pump

Low Pressure Mechanical · 3 Hose Connectors

For scooters with carburetor mounted higher than fuel tank

🔧 Operating Principle

Vacuum Fuel Pumps employ an engine's fluctuation in crankcase pressure to pump fuel from a remote fuel tank to an engine's carburetor.

⚙️ How it works:

As the engine runs, crankcase pressure fluctuates, creating vacuum pulses that actuate the pump diaphragm, delivering fuel intermittently to the carburetor.

📋 Features

Type: Low pressure mechanical fuel pump
Mounting: External, mounted outside the fuel tank
Connectors: 3 hose fittings (inlet, outlet, vacuum)
Application: Scooters with carburetor positioned above fuel tank

📌 Typical use: Many small scooters have the carburetor mounted higher than the fuel tank due to frame design, requiring a vacuum pump to lift fuel to the carburetor bowl.

🔌 Connector Guide

Fuel Inlet Connects to fuel tank

Fuel Outlet Connects to carburetor

Vacuum Port Connects to crankcase or intake manifold

✅ OEM specification replacement: This vacuum fuel pump meets original equipment specifications, designed as a direct replacement for worn or failed pumps. External mounting with 3 hose connectors, ideal for scooters with carburetor positioned above the fuel tank.

⚠️ Please verify your scooter uses a vacuum-operated fuel pump (not electric). This is a low-pressure mechanical vacuum pump designed for applications where the carburetor sits higher than the fuel tank. Check your hose connections and routing before ordering.
