🔌 Function

The engine-driven diaphragm pump uses crankcase pulses or a cam-operated lever to draw fuel from the tank and deliver a regulated low-pressure supply to the carburettor, vapour separator or downstream high-pressure pump.

Common signs of failure:

• Hard starting after the engine has been standing

• Fuel starvation, hesitation or loss of power under load

• Failure to fill the carburettor bowls or vapour separator

• Fuel leaking from the pump body or ruptured diaphragm

• Engine-oil dilution or fuel entering the pulse passage on a failed pump
