Fuel pumps supply the power source of automobiles. A high quality fuel pump, coupled with clean burning fuel, can bring best performance for your automobiles. Today, there are various types of fuel pumps available on the market to match your automobiles, such as car fuel pumps and electric fuel pumps.

Replacement of fuel pump is very important, for if the fuel pump fails in providing required fuel for automobiles for a period of time, there will be lowered performance in the fuel pump.

Before installation of the fuel pump, however, general safety precaution measures should be followed: Disconnect the battery, drain the fuel tank and lift and safely support the vehicle with jack stands. Besides, new fuel filter shall be mounted when replacing new car or truck fuel pump.

• Fire hazards are presented while opening the fuel tank, therefore, all heat sources, flames or sparks should be prohibited and strictly observe fire safety regulations;
• Make sure the power is cut before dismantling the fuel pump;
• There is likely to have pressure inside the fuel tube and cause fuel leakage even when the power is cut, so any cases of heat sources, flames or sparks are prohibited and you should wear gloves and eye shields to protect your eyes;
• There might be fuel left when taking the fuel pump from the fuel tank;
• Fuel leakage test shall be conducted after the fuel pump was installed to ensure that there is no leakage in the interface (including the flange of the assembly), if no leakage test equipment available, please contact professional automobile maintenance station.

• Fuel pump cannot operate without oil;
• Our fuel pump is only suitable for gasoline fuel products with methanol or ethanol contents no more than 10-15%;
• While replacing the fuel pump, the fuel pump filter shall also be changed. Long-term accumulation of dirt in the fuel pump can lead to shorter service life, lowered pressure, declined flow volume, so it is better to have a clean to the fuel tank and relevant pipelines and accessories before installation of new fuel pump;
• If the fuel pump falls to the ground, it is better to check whether the fuel pump is qualified and then confirm whether it can still work. Because, there might be magnet fracture or other magnet defaults, leading to poor performance of fuel pump or other potential hazards (Blocking the motor parts or fuel pipe valve);
• To give your car longer service life, please replace the oil filter within the specified time or distance;
• Make sure that working table and gloves are clean and tidy while mounting the fuel pump to prevent alteration of normal operation of the pump resulting from entering of dust into the pump or pump assembly;
• Fuel should be filled timely under low fuel level and better to fill the fuel when there is about 1/3 fuel within the fuel tank, for the fuel pump will achieve heat dissipation in the operation process of the pump, and when fuel level is too low, there will be poor heat dissipation and can even lead to shorter service life of the pump;
• According to different installation ways, fuel pumps can be divided into two types: built-in pump and external pump. The pumps shall be mounted according to specific pump types and fuse wire must be used for fuel pump power supply line (10A or 15A);

Outlet of built-in pump and inlet and outlet external pump often adopt hose connection (rubber or plastic corrugated pipe), which is disposable and can’t be dismantled unless broken or blocked to ensure normal operation of fuel pump ( including the check valve).
