ISUZU HICOM PERKASA NPR PRO 66 71 4HF1 4HG1 4BE1 HEAVY DUTY DIESEL FUEL FEED AC PUMP MECHANICAL LIFT PUMP (105210-6370-1 / 105210-6370 / 8-97103-625-0)

Overview

The Isuzu / Hicom NPR 4HF1 / 4HG1 Diesel Fuel Feed AC Pump (Mechanical Lift / Transfer Feed Pump 105210-6370-1) is a heavy-duty fuel supply component engineered for Isuzu Elf NPR / NQR series and Hicom Perkasa commercial trucks powered by 4HF1, 4HG1, 4HE1, and 4BE1 diesel engines equipped with Zexel / Diesel Kiki / Bosch inline fuel injection systems. Flange-mounted directly to the side of the inline fuel injection pump, its camshaft-driven internal roller follower draws diesel from the fuel tank under constant low pressure and delivers it through the fuel filtration system into the high-pressure injection pump gallery. Replacing a worn or fatigued AC feed pump restores positive fuel delivery pressure, eliminates air ingress into the diesel circuit, and cures hard cold morning starts, engine hesitations, and power loss under heavy payload acceleration.

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