The harness of vehicle fuel pump interferes with the pressure regulating valve, resulting in damage and short circuit of the harness. How to solve it?

This is what I saw on a wire harness website, and I think it is very good and detailed. I hope it helps you. The wire harness is a multi-strand copper cord with plastic sheath. The temperature in the engine compartment of an automobile is very high, and the plastic will inevitably release chemicals such as plasticizers, which will react with the copper conductor, resulting in the decrease of the strength of the plastic and the increase of the resistance of the copper conductor. In this way, it is easy to lead to the aging of the harness. Aging of engine wiring harness may lead to spontaneous combustion, which should be paid special attention to. After the engine harness is aged, it is easy to be rubbed and worn, resulting in a short circuit with the body. In addition, the temperature in the engine compartment is too high and it is easy to spontaneously ignite.
