DAIHATSU DELTA DV99 DV116 V116 V99 14B 11B DIESEL MECHANICAL FUEL FEED AC PUMP LIFT PUMP (23300-87318 / 2330087318)

Overview

The Daihatsu Delta DV99 / DV116 Diesel Fuel Feed AC Pump (Mechanical Fuel Lift Pump 23300-87318) is a vital fuel system component engineered specifically for Daihatsu Delta commercial trucks (DV99, DV116, V116, V99, V58, V57 series cargo lorries, wooden body trucks, tippers, and box vans powered by 14B, 11B, 13B, and DL diesel engines). Operating as an engine-driven mechanical lift pump (commonly known across workshops as the "AC Pump"), it draws diesel directly from the fuel tank under constant low pressure and feeds it steadily through the fuel filter unit into the fuel injection pump. Replacing an aged, stiff, or leaking mechanical AC pump cures hard cold starting, eliminates engine hesitation and power loss when carrying heavy payloads, and prevents diesel starvation caused by internal diaphragm fatigue or sticking check valves.

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