🔌 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

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
