NISSAN DIESEL UD QUON BIG THUMB CD4 CD48 CG4 CV4 GW GE13 GE13TC HEAVY DUTY DIESEL FUEL FEED AC PUMP LIFT PUMP (16640-00Z0A / 1664000Z0A)

Overview

The Nissan Diesel UD GE13 / CD4 Diesel Fuel Feed AC Pump (Mechanical Fuel Feed Lift / Transfer Pump 16640-00Z0A) is a heavy-duty fuel supply component engineered for Nissan Diesel (UD) Quon, Big Thumb, and heavy commercial transport trucks powered by GE13, GE13-TC, GE13-TD, and GEB3 diesel engines (CD4, CD48, CD5, CG4, CG5, CK48, CV4, CV48, and GW heavy prime movers, tippers, cargo lorries, container haulers, and concrete mixers). Mounted directly to the engine gear casing / fuel pump drive assembly, this engine-driven fuel feed pump (universally termed in commercial workshops as the "AC Pump" or "Feed Pump") draws diesel fuel from the fuel tank under constant positive pressure and delivers it steadily through the primary filtration system into the engine injection gallery. Replacing an aged or worn AC feed pump restores steady fuel supply pressure, cures prolonged morning cranking, prevents air ingestion into the diesel supply circuit, and eliminates fuel starvation, engine hesitation, or power loss under heavy highway hauling payloads.

Engineered to heavy commercial fleet specifications for dependable workshop replacement, fuel system overhaul, and engine chassis maintenance.
