294000-1710 22100-0L100 High Quality Common Rail Diesel Fuel Injector Pump for

Product Specifications

Product Overview

This 294000-1710 high-pressure fuel pump is a core component of the electronically controlled common rail fuel supply system, specifically designed for Hino J05E/J08E series engines. It is widely used in various medium-duty trucks and industrial machinery. Its core function is to precisely boost low-pressure fuel to ultra-high pressure and, through electromagnetic metering unit control, ensure a constant and precise fuel flow within the high-pressure rail. In actual use, users will immediately experience a significant improvement in engine start-up response. Even under harsh conditions such as fully loaded uphill climbing, power output remains continuous, effectively eliminating the jerking sensation caused by unstable fuel supply. We have adopted high-pressure resistant sealing reinforcement technology, greatly improving the pump body's stability and durability in complex operating environments. It is a key upgrade configuration to ensure continuous high-efficiency operation of your machinery and optimize fuel combustion performance.

Product Advantages

With our vertically integrated in-house manufacturing plant, we have achieved a fully self-managed closed loop from the processing of key precision components to the finished product rollout. This not only optimizes procurement budgets at the source but also ensures that our products maintain a high degree of consistency with original equipment manufacturer (OEM) specifications across all key indicators, providing you with industry-class performance assurance.

We have built a high-speed, readily available warehousing system. Addressing the severe business impact of unplanned equipment downtime in commercial operations, we have established a professional shipping and logistics chain to ensure that orders are shipped out immediately after processing, helping your equipment to be replaced and returned to busy engineering work as quickly as possible.

We implement comprehensive precision performance quality inspection standards. Every 294000-1710 high-pressure oil pump undergoes high-pressure bench calibration and flow accuracy testing under simulated real-world operating conditions before leaving our warehouse. This successfully avoids the risks of fuel pressure fluctuations and low combustion efficiency caused by low-end parts on the market, giving you the peace of mind and stability of having brand-new OEM parts.

Technical Parameters

Application Scenarios

In busy urban distribution logistics networks, commercial trucks require frequent start-stop operations and short-distance, high-intensity transportation. When the original fuel pump experiences abnormal starting or power loss during driving due to pressure decay from long-term operation, installing this precision high-pressure fuel pump can quickly restore the linearity and stability of the fuel supply. Drivers can clearly feel a smoother start at intersections, and the improved fuel combustion directly optimizes daily fuel costs, significantly improving the overall turnaround efficiency of the vehicle under high-frequency operation.

In large, remote ore transshipment sites, heavy machinery needs to continuously transport equipment at full load in dusty, vibrating, and high-load environments. Faced with the common challenges of torque limitation or inability to climb hills under complex operating conditions, this high-pressure fuel pump, with its superior pressure build-up performance and durability, ensures that the engine can still provide continuous and stable power support when the load changes abruptly. This not only guarantees the continuous operation of construction tasks under harsh conditions but also avoids the risk of equipment being stranded in the field due to fuel supply system failures.

Frequently Asked Questions

• Q: Is it necessary to replace the fuel filter simultaneously when installing this pump? A: It is strongly recommended to replace the fuel filter with a brand new, high-quality one. The new pump has a precise internal structure, and pre-filtering tiny particles in the fuel effectively protects component life.
• Q: I found a few oil stains on the product after receiving it. Is this a product defect? A: This is professional anti-rust oil applied before shipping to prevent oxidation and rust on precision metal parts during transportation. It's a normal part of the manufacturing process and can be used directly without pre-wiping.
• Q: Do you provide after-sales service for this high-pressure oil pump? A: We provide industry-standard quality assurance for all products we sell. If the abnormality is verified to be caused by the manufacturing process, we will provide you with a fast replacement service to ensure the operational benefits of your equipment.
• Q: What should I do if the dashboard shows a fault light after replacing the oil pump? A: We recommend using dedicated diagnostic equipment to reinitialize and calibrate the fuel pressure and fuel metering unit parameters after installation. If the fault light persists, please contact our customer service for technical support.
• Q: Can this pump use ordinary fuel? A: Although this part has excellent corrosion resistance, to ensure its long-term efficient operation, we still recommend using clean diesel fuel that meets industry standards and performing regular fuel system maintenance.
• Q: Do you support large-volume purchase orders for logistics companies? A: We warmly welcome logistics fleets and repair centers to discuss large-volume cooperation, and will provide you with more competitive tiered wholesale prices and specialized technical support services.
