1154158450 Original Excavator Fuel Pipe for ISUZU 6BG1 ENGINE

The original fuel pipe part number 1154158450 (or similar number 1-15415845-0) is a critical pipeline for the high-pressure fuel system of the ISUZU 6BG1 diesel engine (displacement 6.494L, power approximately 153kW). This fuel pipe is mainly suitable for excavators from brands such as Hitachi and Shengang equipped with 6BG1 engines, such as ZX200, ZX230, ZX270, EX200, ZAX200, etc. Its common number is often labeled as series numbers 1-15415847-0, 1-15415848-0, etc., corresponding to the high-pressure oil pipe from the fuel injection pump to the fuel injector of each cylinder of the engine. When placing an order, the engine model and specific cylinder sequence must be provided to ensure that its length, interface threads, and original pipelines are fully matched.

This product is an original high-pressure fuel pipe, usually made of seamless steel pipe material. The inner wall is precision machined to ensure smooth and sealed fuel flow. Its typical specifications are an outer diameter of 6mm, an inner diameter of 4mm, a wall thickness of 1mm, and a specific bending radius (such as 180mm) to accommodate the compact layout of the engine compartment. Both ends are equipped with metal cone sealing joints or copper gaskets for sealing, which can withstand injection pressures of up to 20-30MPa in direct injection fuel systems. As an original component, its material strength, corrosion resistance, and sealing performance are strictly matched with the mechanical fuel injection system of the 6BG1 engine, ensuring reliable sealing and long service life under high temperature, high pressure, and high vibration conditions.

It is recommended to check all high-pressure oil pipes for leaks, cracks, bulges, or loose joints every 250 working hours; Pay special attention to whether the sealing cone surfaces at both ends of the fuel injection pump and nozzle are intact. Installation points: When replacing, use a special wrench to tighten the joint in diagonal order to avoid leakage or thread damage caused by uneven force; After installation, it is necessary to exhaust the air in the fuel system (pump oil through the hand pump until there are no bubbles at the outlet of the oil pipe). Preventive replacement: The high-pressure oil pipe is a vulnerable part, and it is recommended to replace it together during the engine overhaul (about 8000-10000 hours), or if oil stains, rust, or deformation are found on the surface, it should be replaced in advance.
