🔌 Function

The high-pressure electric pump supplies the pressure and flow required by the EFI fuel rail and injectors. It normally operates inside a vapour separator or cooled fuel module.

Common signs of failure:

• Low or unstable fuel-rail pressure

• Crank/no-start or difficult hot starting

• Engine hesitation, lean surging or loss of power

• Pump noise, excessive current draw or blown fuse

• Intermittent stalling as the pump or fuel module heats up

📦 Condition

• Brand new

• Supplied in original or equivalent packaging
