To replace the fuel pump of the JAC Ruifeng 7-seater utility vehicle, the fuel tank must be removed.
Because the fuel pump of the JAC Ruifeng 7-seater utility vehicle is just above the fuel tank.
The function of the fuel pump is to suck gasoline from the fuel tank and squeeze it into the float chamber of the carburetor through the pipeline and fuel filter. Thanks to the fuel pump, the fuel tank can be placed at the rear of the car, away from the engine and lower than the engine. According to different driving methods, fuel pumps can be divided into mechanically driven diaphragm types and electrically driven types.

Before installing the oil pump in the generator set, checkif the model and specifications are correct, and remove the anti-rust oil. The thickness of the joint must be. appropriate to prevent the piston from being pushed or stuck. If the operation is not in place, the gasket should be avoided too thin or too thick, and the tightening torque should be uniform when tightening the bolts to avoid damage to the oil. pump.
Ensure that the elasticity of the four springs of the piston oil pump is normal. The four springs are the piston spring, the lifter (roller) spring, the oil inlet valve spring and the oil outlet valve spring. If the elasticity of the spring is weakened or broken, it should be replaced or padded in time to avoid damage to the generator set.

The precise engine number of Ruifeng is located under the exhaust branch pipe on the right side of thecast iron cylinder, near the fan wheel. There is a rectangular plane on the cylinder with the engine number engraved on it.
The engine number is the same as the VIN number of the car. The engine number is unique. Different manufacturers have different classifications of engine numbers and what's in them. It typically includes the engine model, year and month of production, and the serial number randomly assigned to the engine when it left the production line. Some also include the original code, provided the engine was produced to standards. of the automobile brand.

Remarks:
Car engine During operation, carbon deposits will occur in the fuel injector, ignition head, valve, cylinder top, piston working surface, piston ring groove, etc. Atover time, carbon deposits appear in the form of colloidal deposits, which will cause the volume of the combustion chamber to decrease and work efficiency to deteriorate.
Many uneven hot spots appear during the combustion process, causing premature combustion of the mixture, resulting in reduced efficiency, incomplete combustion, increased exhaust gas emissions, poor fuel supply. fuel and poor ignition, unstable idling and misfiring. Detonation blocks the piston ring groove, causing poor lubrication of the cylinder, thereby contaminating the lubrication system, blocking the oil circuit and oil filter, etc. Therefore, the engine fuel system requires cleaning and maintenance.
