NISSAN DIESEL UD BIG THUMB RESONA RF8 RD8 RE8 RG8 HEAVY DUTY DIESEL FUEL FEED AC PUMP MECHANICAL LIFT PUMP (105237-4000 / 1052374000 / 105217-4000 / 1052174000)

Overview

The Nissan Diesel UD RF8 Diesel Fuel Feed AC Pump (Mechanical Lift / Transfer Feed Pump 105237-4000) is a heavy-duty fuel supply component engineered for Nissan Diesel (UD) Resona, Big Thumb, and heavy commercial vehicles powered by RF8, RD8, RE8, and RG8 V8 diesel engines equipped with Diesel Kiki / Zexel / Bosch inline fuel injection systems (heavy dump trucks, tippers, cargo lorries, concrete mixers, prime movers, and heavy haulers). Flange-mounted directly to the side of the inline fuel injection pump, its camshaft-actuated roller follower draws diesel from the fuel tank under constant positive 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 steady fuel supply pressure, cures prolonged morning hard starts, prevents micro-air ingress into the fuel line, and eliminates fuel starvation, engine hesitation, or power loss under heavy payload haulage.

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