🔌 Function

The diaphragm pulses with crankcase pressure to move fuel through the carburettor-mounted fuel pump. The gaskets and seals prevent air and fuel leaks so the pump can maintain steady fuel delivery.

⚠️ Common Signs of Failure

• Hard starting after sitting
• Fuel starvation at idle or under throttle
• Engine surging from weak fuel pump pulse
• Fuel leaking from pump cover
• Diaphragm stiff, cracked or distorted
• Poor fuel delivery after carburettor rebuild
