Here’s a rephrased version of each line to avoid duplicate semantics:
【Material Upgrade】: The connector of the oil return line assembly is made of brass with nickel-plated surface treatment, which is strong and durable, and more corrosion-resistant. The oil return hose is made of oil-resistant nitrile rubber, and the thickened nylon protective layer not only insulates but also increases the abrasion resistance and elasticity of the fuel line
【Functions】:Old fuel return hose assemblies are prone to breaking during disassembly or leaking due to cracks and heat stress.Replacing the oil return hose assembly will quickly solve this problem
