094000-0273 1-15603239-2 Diesel Engine Fuel Injection Pump for Isuzu

This high-performance diesel engine high-pressure fuel pump (OE No.: 094000-0273) is specifically designed for heavy-duty construction machinery and heavy-duty truck high-pressure common rail systems. It is perfectly compatible with classic models such as the Komatsu PC400-7 and PC450-7, as well as high-power diesel engines like the Komatsu 6D125 and SAA6D125E. As the core "heart" of the fuel injection system, it employs cutting-edge ultra-high pressure precision manufacturing technology to provide the engine with stable, precise, and continuous fuel atomization pressure. After installing this high-pressure fuel pump, you will immediately feel your previously sluggish engine regain its powerful performance. Every time you press the accelerator, the power response becomes extremely sensitive and smooth. Simultaneously, thanks to the improved fuel atomization effect, the previously harsh engine knocking noise is significantly reduced, and black smoke completely disappears. The equipment exhibits reassuring stability and high efficiency under high load conditions.

• Direct Sales from Our Own Factory and Ample Stock:
  Addressing the common challenges faced by international buyers, such as long procurement cycles and production stoppages due to stock shortages, we maintain a large inventory of this model of high-pressure oil pumps in our own modern factory. This effectively shortens your waiting time, enabling rapid, lightning-fast delivery after ordering, allowing your machinery to resume operation in the shortest possible time and minimizing significant losses due to downtime.
• Rigorous Quality Control and Extended Lifespan:
  Addressing the issues of poor wear resistance and internal leakage leading to difficult hot starts in similar products on the market, every high-pressure oil pump we manufacture undergoes rigorous testing on a high-precision fuel injection test bench. From housing airtightness to the high-pressure oil return volume of the plunger assembly, we implement full-process digital monitoring to ensure that the product maintains zero internal leakage and high wear resistance even under extreme high-temperature and high-pressure environments, bringing customers sustained and stable operational returns.
• Original Factory Grade Craftsmanship and Exceptional Fuel Efficiency:
  Addressing the persistent fuel system problems caused by inferior fuel pumps, such as poor atomization, soaring fuel consumption, and excessive emissions, this product is manufactured strictly according to OEM standards, with internal core component clearances down to the micron level. This not only completely solves the problem of incomplete fuel combustion caused by pressure fluctuations but also significantly improves fuel economy, helping end-users substantially reduce daily fuel costs and achieve lower emissions.

• Large-scale mining and earthmoving operations:
  In dusty, high-load open-pit mines, the Komatsu PC400-7 excavator is performing heavy-load loading. Operators frequently perform complex maneuvers, requiring uninterrupted power delivery. Equipped with the 094000-0273 high-pressure fuel pump, the engine can instantly establish ultra-high rail pressure when excavating hard rock, providing a stable fuel flow rate to ensure powerful arm digging without stalling or slowing down, efficiently completing high-intensity mining tasks.
• Long-distance heavy-duty logistics transportation and high-altitude mountain crossings:
  Heavy-duty trucks equipped with this power system are fully loaded with goods traveling on undulating national highways or high-altitude uphill sections. Drivers need to frequently accelerate at high speeds when facing steep slopes. At this time, the high-pressure fuel pump precisely outputs ultra-high-pressure fuel according to ECU commands, ensuring extremely fine fuel atomization from the injectors. The product fully ensures that the engine can generate high torque even at low speeds, easily handling long-distance uphill climbs and effectively avoiding frequent gear shifts and engine overheating due to insufficient power.
• Construction Projects and Urban Infrastructure Construction:
  In urban infrastructure construction sites with tight schedules, the PC450-7 crusher is performing continuous concrete crushing operations. Due to high ambient temperatures and variable loads, operators need to keep the equipment running at high idle speed or full power for extended periods. This high-pressure oil pump, with its excellent heat dissipation and internal wear-resistant design, maintains zero fuel pressure fluctuations even during dozens of hours of continuous operation, ensuring the equipment does not shut down due to oil circuit problems and perfectly keeps up with project schedules.

1. Q: My equipment is a Komatsu PC400-7, but I'm unsure of the specific engine model. Can it be installed directly?
   A: The 094000-0273 is a very classic high-pressure oil pump for the Komatsu 6D125/SAA6D125E engine. To ensure 100% compatibility, we recommend checking the 10-digit code on the original pump's nameplate before placing your order, or sending your VIN to our online customer service. We will provide you with a free, accurate, big data-driven vehicle comparison.
2. Q: Does the product come with a warranty? What if I find damage during shipping after receiving the goods?
   A: We offer a 6-12 month extended warranty on every high-pressure oil pump we sell. All products undergo rust-proof and high-specification shockproof packaging before leaving the factory. If you find damage to the outer packaging or shipping damage to the product upon receipt, please take photos and contact us immediately. We will arrange for a free replacement or a full refund.
3. Q: Do you have stock available? How long does it take to deliver to an overseas address after placing an order?
   A: As we are a factory direct seller, we maintain a large inventory of this popular model in our warehouse. Typically, your order will be shipped and delivered via DHL/FedEx/UPS or other international express courier services within 48 hours of placement. Delivery to major countries in Europe, America, and the Middle East typically takes 5-7 business days.
4. Q: Are there any special installation recommendations when replacing a new high-pressure fuel pump?
   A: Before installing a new high-pressure fuel pump, please thoroughly clean or replace the diesel fuel tank and fuel lines, and replace the fuel filter with a brand new, high-quality one. This is because trace impurities and moisture in diesel fuel are the main causes of wear on precision components in the high-pressure common rail system. Keeping the fuel system clean can extend the life of the new fuel pump several times over.
