NISSAN DIESEL UD RD8 HINO SUPER DOLPHIN EK100 HEAVY DUTY DIESEL FUEL FEED AC PUMP MECHANICAL LIFT PUMP (105217-4000-1 / 105217-4000 / 1052174000)

Overview

The Nissan Diesel UD RD8 & Hino EK100 Diesel Fuel Feed AC Pump (Mechanical Lift / Transfer Feed Pump 105217-4000-1) is a heavy-duty fuel supply component engineered for Nissan Diesel (UD) heavy trucks and Hino heavy commercial vehicles powered by Nissan RD8, RD10, RE8 and Hino EK100, EM100, EP100, and EF750 diesel engines equipped with Diesel Kiki / Zexel / Bosch inline fuel injection systems (Super Dolphin, Resona, Big Thumb heavy dump trucks, tippers, cargo lorries, concrete mixers, and prime movers). Operating as an engine-driven mechanical lift pump mounted directly to the side of the inline fuel injection pump, its camshaft-actuated roller follower draws diesel from the fuel tank under constant low pressure and feeds it steadily through the fuel filtration system into the high-pressure injection pump gallery. Replacing a worn or fatigued AC feed pump restores steady fuel supply pressure, cures prolonged morning hard starts, prevents air ingress into the fuel line, and eliminates fuel starvation or power loss under heavy payload acceleration.

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