Essential Role of Fuel Pipe Inner 160101120038A015 in the Fuel Delivery Circuit

The SANY Fuel Pipe Inner, identified by part number 160101120038A015, operates within the low-pressure side of the fuel system. Its primary function is to transport diesel fuel from the vehicle’s fuel tank, through filters and water separators, and onward to the fuel transfer or injection pump. Operating at pressures significantly lower than the high-pressure injection lines, the 160101120038A015 is nonetheless critical for system priming and maintaining a steady, bubble-free fuel supply. It ensures that the high-pressure pump receives fuel consistently, which is paramount for preventing cavitation and maintaining correct injection timing and pressure.

A compromised 160101120038A015 pipe can introduce air into the fuel system, leading to hard starting, engine misfires, power loss, and even unexpected stalling. It can also cause external leaks, which are wasteful, environmentally hazardous, and pose a fire risk. Therefore, while it may not endure the extreme pressures of the injection rail, the integrity of this inner fuel line, part number 160101120038A015, is fundamental to the overall reliability and efficiency of the engine’s fuel delivery process.

Construction and Material Specifications for Durability

The genuine 160101120038A015 Fuel Pipe Inner is typically constructed from high-quality, fuel-resistant synthetic rubber or reinforced thermoplastic. This material is specifically formulated to withstand prolonged exposure to modern diesel fuels, including biodiesel blends, without degrading, swelling, or becoming brittle. The pipe is designed with a smooth inner bore to minimize flow resistance and prevent fuel contamination from flaking or peeling of the inner liner.

The following table provides the key technical specifications for the SANY Fuel Pipe Inner. These details are crucial for correct part identification and to ensure compatibility with the vehicle’s specific fuel system layout and requirements.

Correct Installation and Maintenance Guidelines

Proper installation of the 160101120038A015 Fuel Pipe Inner is essential for a leak-free and reliable fuel system. Before installation, inspect the new pipe for any shipping damage. Clean the mating surfaces on the fuel filter, pump, or tank connections. Use new sealing washers (e.g., copper or aluminum crush washers for banjo fittings) as specified by SANY. When tightening the fittings, use a torque wrench to achieve the manufacturer’s specified torque value. Over-tightening can damage the fittings or strip threads, while under-tightening will cause leaks.

Route the 160101120038A015 pipe exactly along the factory path, securing it with all designated clips and brackets. Avoid sharp bends, kinks, or contact with hot surfaces or moving parts. After installation, prime the fuel system according to the service manual to remove air. Start the engine and carefully inspect the entire length of the new pipe and all connection points for any signs of fuel seepage. Regular visual inspections during service intervals for cracks, abrasions, or softening are recommended preventative maintenance for this component.

Identifying Failure and Diagnostic Procedures

Failure of the Fuel Pipe Inner 160101120038A015 typically manifests in several ways. The most common symptom is a visible fuel leak, often detected by wet spots, drips, or a strong smell of diesel in the vehicle’s undercarriage or engine bay. Air ingress through a cracked or porous hose can cause engine starting difficulties, rough idling, hesitation under acceleration, and white smoke from the exhaust due to lean combustion. A severely restricted or kinked pipe can lead to fuel starvation, resulting in engine power loss or stalling, especially under load.

Diagnosis involves a thorough visual and physical inspection. Check the entire hose for cracks, bulges, abrasions, signs of weathering, or soft, spongy spots. Inspect fittings for corrosion or looseness. A vacuum test on the supply side or a fuel pressure test can help identify restrictions or leaks not visible to the eye. If any damage is suspected, the 160101120038A015 should be replaced immediately with a genuine part to restore system integrity.
