To replace the gasoline pump of JAC Ruifeng 7-seater commercial vehicle, the fuel tank must be removed.
Because the gasoline pump of JAC Ruifeng 7-seater commercial vehicle is right above the fuel tank.
The function of the gasoline pump is to suck gasoline from the fuel tank and press it into the float chamber of the carburetor through the pipeline and gasoline filter. Thanks to the petrol pump, the petrol tank can be placed at the rear of the car, away from the engine and lower than the engine. According to different driving methods, gasoline pumps can be divided into mechanically driven diaphragm type and electrically driven type.
Extended information:
Before installing the oil pump in the generator set, check whether the model and specifications are correct, and remove the anti-rust oil. The thickness of the gasket should be appropriate. In order to avoid the piston being pushed or blocked If the operation is not in place, the gasket should be prevented from being too thin or too thick, and the tightening torque should be uniform when tightening the bolts to prevent damage to the oil pump.
Ensure that the four springs of the plunger oil pump have normal elasticity. The four springs are the piston spring, tappet (roller) spring, oil inlet valve spring, and oil outlet valve spring. If the spring elasticity is weakened or broken, it must be replaced or padded in time to avoid damage to the generator set.

1. The generator is broken (this situation rarely happens, replace the generator or repair the generator ).
2. The generator regulator is broken (Ruifeng is prone to this common problem, so replace the regulator).
3. The power generation output terminal has poor contact (very rare, clean the dirt and tighten the terminals).
4. The battery does not store electricity (it may be that after the generator regulator is broken, the generated voltage is high and the battery is burned out. Inspection method: 1) Check whether the battery water is turbid. If it is turbid, it means it is burned out. of. Be sure to repair the generator and replace the regulator. Otherwise, the new battery will burn out. 2) Use a meter to measure the power generation voltage. If the idle speed is lower than 13.8v and the full throttle is higher than 14.8v, there is a problem with the regulator.)
5. The belt is loose and the power generation is not enough (it is easy to happen, especially for diesel Ruifeng, Just loosen the tight belt. If it is a diesel engine, carefully check whether the connecting hole between the generator and the engine is worn and if it is loose, repair it in time.)
