Introduction

Speaking of fuel pumps, most car owners may not know what this is. Today we will understand that the fuel pump is installed at the lowest part of the fuel tank and its job is to pump fuel to the engine.
In fact, the fuel pump is equivalent to the heart in our body. It is responsible for transporting blood to the body, so if the gasoline pump is broken or blocked, it cannot deliver fuel to the generator.

Fuel pump installation loion

The fuel pump is loed in the car's fuel tank, which is loed in the rear seat of the car, or under the trunk. The main function of the fuel pump is to supply fuel to the engine. The fuel pump delivers the high pressure and high pressure fuel pump to the fuel distribution pipe to ensure continuous fuel supply to the fuel injection nozzle. The fuel pump is composed of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the oil pump housing, don’t worry, because there is nothing in the housing that can be ignited, the fuel can lubrie and cool the fuel motor, the oil outlet is equipped with a check valve, and the pressure limiter is loed at the pressure of the oil pump housing On the side, there is a channel leading to the oil inlet.
Built-in: integrated with the assembly, installed vertically in the mailbox. Features: Low noise, not easy to produce air resistance. The safety pipeline is easy to install.
External type: connected in series in the oil pipeline outside the mailbox. It is characterized by large installation freedom, convenient replacement and high air-tightness requirements.
At present, the fuel pump of most models is installed in the car mailbox and driven by electricity. The fuel pump is composed of a pump body, a permanent magnet motor and a shell. When the permanent magnet motor is energized, the pump body is driven to rotate, and the fuel is sucked in from the fuel inlet, flows through the inside of the electric fuel, and then is pressed out from the fuel outlet to supply fuel to the fuel system. The fuel flows through the inside of the electric fuel to cool the armature of the permanent magnet motor, also known as the wet fuel pump.

How to tell if the fuel pump is broken

Method 1: Turn on the ignition switch, do not start the engine, you can hear the petrol pump working for 1-2 seconds, you can judge whether the petrol pump is working.
Method 2: Unplug the fuel pump relay, connect the fuel pump circuit with a dedied jumper, turn on the ignition switch, do not start the engine, the fuel pump can work, indiing that the fuel pump is normal.
Method 3: Connect the oil pressure gauge to see if the engine can build up the oil pressure of about 250KPA, and if the oil pressure builds up quickly, if the oil pressure can be established normally, the oil pump can work. Then turn off the engine ignition switch to see if the oil pressure is quickly released (whether the oil pressure drops quickly) to determine whether the pressure relief valve of the oil pump is normal (normal oil pressure can be maintained so that the engine can start normally next time).
Method 4: Connect the circuit to the fuel pump, and use a special measuring tool (such as a beaker) to measure whether the fuel output and return of the fuel pump are normal.
