Material and Design of Fuel‑inlet Pipe Assembly 160102130003A105

The fuel‑inlet pipe assembly 160102130003A105 is manufactured from seamless cold‑drawn carbon steel (ST37.0 / 1010 equivalent). The tube has an outer diameter of 8 mm and an inner diameter of 5 mm, with a wall thickness of 1.5 mm. The tube is mandrel‑bent to a specific 3D shape using CNC bending machines, ensuring smooth internal flow without kinking. The overall length is 320 mm ±1 mm, with two 90° bends and one 45° bend.

Both ends are precision‑flared to accept high‑pressure fittings. One end has a male cone (24° DIN 2353) for a union nut (M12 x 1.5), and the other end has a permanently swaged steel fitting with a captive O‑ring (size 2‑011). The assembly is designed to connect the fuel filter outlet to the injection pump inlet on SANY D07/D09/D12 engines. The pipe includes a protective plastic sleeve where it passes through the engine bracket.

The external surface is zinc‑nickel plated (8-12 µm) with black trivalent passivation, providing 500 hours of salt spray resistance (ASTM B117). This coating resists corrosion from diesel fuel, biodiesel, and road salt. The assembly weight is 0.28 kg. The pipe is rated for a working pressure of 2000 bar (common‑rail) and a burst pressure of 4000 bar. For mechanical injection systems, the working pressure is 350 bar.

All 160102130003A105 assemblies are 100% pressure‑tested at 3000 bar for 60 seconds with no leakage. A sample from each batch is burst‑tested to 4000 bar minimum. Dimensional verification is performed using a CMM fixture. A laser‑etched batch code on the tube provides full traceability to the tubing lot, bending program, and inspection date.

Function of Fuel‑inlet Pipe Assembly 160102130003A105 in Fuel System

The fuel‑inlet pipe assembly 160102130003A105 delivers pressurized diesel fuel from the fuel filter to the high‑pressure injection pump (or common rail). In a common‑rail system, the pump supplies fuel at up to 2000 bar to the rail, and this pipe must withstand extreme pressure pulses without leaking or bursting. In mechanical systems, it handles lower pressures but still requires absolute integrity.

A cracked or leaking inlet pipe will cause fuel starvation, hard starting, loss of power, and a strong diesel odor. Air ingress through a leak will cause rough running and white smoke. The pipe must be handled with extreme care – nicks or scratches on the sealing cones can cause leaks. Always use new sealing washers or O‑rings when reinstalling.

On SANY D07/D09/D12 engines, this pipe is located on the engine side, connecting the filter head to the injection pump. It is often removed during fuel filter changes or injection pump service. Replace the pipe if it is bent, kinked, or shows any signs of corrosion.

Compatible SANY Models & Interchange Information

The fuel‑inlet pipe assembly 160102130003A105 is used on SANY D07, D09, and D12 series diesel engines. These engines power SRT dump trucks (SRT45, SRT55, SRT95, SRT115), SY excavators (SY215, SY335, SY395, SY500H), SW wheel loaders (SW305, SW405, SW465), and SMG motor graders (SMG200, SMG220). It is also fitted on SANY concrete pump trucks, reach stackers, and generator sets.

The pipe fits banjo fittings (M12 x 1.5) with a copper sealing washer at one end and a threaded port with O‑ring at the other. Always verify the original pipe shape and length. When ordering, specify 160102130003A105 to receive the correct tube routing, end fittings, and zinc‑nickel coating.

For fleet maintenance, stock genuine 160102130003A105 pipes. Aftermarket pipes often use welded‑seam tubing that splits under high pressure, or they have incorrect bend angles, causing kinking. Genuine SANY pipes guarantee seamless construction, correct flare dimensions, and corrosion resistance.

Proper Installation of Fuel‑inlet Pipe Assembly 160102130003A105

Before installing the pipe assembly 160102130003A105, clean the filter outlet port and the pump inlet port. Use new copper sealing washers on the banjo bolt (two required). Do not reuse old washers. Lubricate the O‑ring at the swaged end with clean diesel fuel. Hand‑start the banjo bolt, then tighten to 25 Nm. For the O‑ring end, tighten the union nut to 30 Nm.

Route the pipe away from hot surfaces (exhaust manifold) and moving parts. Ensure the pipe does not contact the engine block or sharp edges – use the provided plastic sleeve or spring clips. After installation, prime the fuel system and check for leaks at both ends. If a leak is detected, do not over‑tighten – replace the sealing washers or the O‑ring.

Never reuse a pipe that has been bent or kinked. Do not attempt to straighten a kinked pipe – replace it. Store new pipes in a dry, clean environment. Use only genuine SANY pipes for guaranteed pressure rating and leak‑free operation.

Symptoms of a Failed Fuel‑inlet Pipe Assembly 160102130003A105

A failed 160102130003A105 pipe will show external fuel leakage at the fittings or along the tube. You may see wet diesel stains or smell fuel. A cracked pipe under high pressure may spray diesel, creating a fire hazard. If air is sucked in through a leak, the engine will run rough, misfire, and produce white smoke. Hard starting and loss of power are also common.

A kinked pipe will restrict fuel flow, causing low power and black smoke under load. A corroded pipe (red rust) indicates coating failure – replace it. A missing or damaged O‑ring will cause immediate leakage at the threaded connection. A loose banjo bolt will also leak, often due to worn sealing washers.

During preventive maintenance, inspect the pipe for chafing, kinks, or corrosion. Replace the pipe every 8,000 hours or if any damage is found. Use only genuine SANY pipes for replacement.

Quality Assurance & Full Traceability for 160102130003A105

Every fuel‑inlet pipe assembly 160102130003A105 is manufactured in an IATF 16949 certified facility. The raw steel tube is tested for tensile strength and chemical composition. Bending is performed on CNC mandrel benders, and each tube is 100% checked for dimensional accuracy using a laser measurement system. The zinc‑nickel coating thickness is verified by XRF.

A sample from each batch is subjected to pressure cycling (0‑2000 bar, 100,000 cycles) with no leakage or cracking. Burst testing is performed to 4000 bar. Salt spray testing (500 hours) verifies coating integrity. A laser‑etched batch code on the tube provides traceability to the tubing lot, bending machine, and assembly date.

For bulk orders, SANY provides a Certificate of Conformance (CoC) confirming that all 160102130003A105 pipes meet material, dimensional, and pressure specifications. Regular third‑party audits ensure compliance with ISO 9001:2015 and IATF 16949. Trust only genuine SANY pipes for leak‑free fuel delivery.

Field Performance of Genuine SANY Fuel‑inlet Pipe Assembly

Field data from SANY equipment operating in Australian mines and Brazilian sugarcane fields shows that genuine 160102130003A105 pipes last over 15,000 hours without leakage or cracking. The seamless steel construction resists fatigue, and the zinc‑nickel coating prevents rust even in high‑humidity environments. The sealing cones maintain integrity through thousands of thermal cycles.

Aftermarket pipes often use welded‑seam tubing that fails under high pressure, or they have poor flare geometry causing immediate leaks. Their coatings may be thin, leading to rust within 2,000 hours. Genuine SANY pipes eliminate these risks. Fleet owners report 95% fewer fuel inlet pipe failures after switching to genuine pipes.

To maximize service life, always replace the pipe when the fuel system is opened. Use new sealing washers and O‑rings. Inspect the pipe for chafing at every service. Following these practices ensures reliable fuel delivery and engine performance.
