Product Description

This professional high-pressure common rail diesel pump is developed for high-intensity light trucks and commercial vehicles, serving as a pressure-stabilizing core to sustain powerful hauling capacity. Adopting a high-precision digital pumping system, it delivers consistent abundant rail pressure around the clock. After replacement, sluggish, sticky takeoff power is completely eliminated, and the throttle responds sharply and smoothly. Even when climbing mountains with full loads, the engine releases sustained powerful pulling torque.

Product Advantages

Dynamic Digital Control Valve Regulates Pressure to Maximize Diesel Power Output

Built with a factory-spec resistance Suction Control Valve (SCV) that detects throttle position within microseconds and precisely adjusts fuel intake volume into the plunger chamber. Optimized fuel pressure management enables complete fuel atomization and combustion at idle, low speed and high-speed cruising, fundamentally resolving weak acceleration and drastically cutting black exhaust smoke.

Nitride-Quenched Key Structures Deliver Excellent Anti-Seize & Wear Resistance

Commercial fleets frequently encounter fuel contaminated with moisture, particles and low-lubricity low-sulfur diesel. Core plunger assemblies are forged from high-strength precision tool steel and processed with multi-step deep carbonitriding quenching treatment. The ultra-low-friction outer layer provides superior self-lubrication, effectively preventing mechanical abrasion and internal leakage to guarantee all-day high uptime.

1:1 OE Digital Prototyping Passes ECU Self-Diagnosis Without Fault Codes

Precision mass-produced fully compliant with OE factory standards. Fuel inlet/return port spacing, flange shoulder angles and drive shaft dimensions match original equipment 100%. Electrical component resistance values fully conform to OEM requirements. No wiring cutting or secondary modifications are needed during installation. The ECU establishes stable system communication instantly after fitting, clearing warning lights caused by uneven oil pressure and eliminating speed-limited limp mode.

Parameter Table

Compatible Vehicle & Equipment Models

This electronic high-pressure common rail diesel pump fits light trucks and commercial vehicles equipped with Isuzu 4JJ1 3.0L electronic common rail turbo diesel engines, including Nissan and Isuzu models with identical powertrains:

· Isuzu Elf / N-Series Light Trucks NHR / NKR / NPR 3.0 TD (4JJ1 engine variants)

· Isuzu D-Max High-Power Pickup 3.0 TD with 4JJ1 engine

· Nissan Atlas Light Truck 3.0 TD (Isuzu OEM-equipped 4JJ1 models)

· General construction machinery: Hydraulic excavators, forklifts and other units fitted with industrial Isuzu 4JJ1 common rail engines

Professional Selection Tip: The Isuzu 4JJ1 engine has a long production lifespan. Fuel pumps feature updated flow codes for regional emission standards (China NR III, China NR IV, Euro 4) and power tuning iterations. Part number 294000-0571 shares highly similar appearance and partial interfaces with the later 294000-1190 series, yet carries slightly adjusted SCV injection curves. To restore full vehicle performance reliably, disassemble and inspect your original pump before ordering to confirm the part number 294000-0571 or Nissan OEM code 16700-89T0J stamped on the housing or nameplate.
