fuel level sensor with float
The fuel level sensor is used to monitor the amount of fuel in the fuel tank and feed back the information to the instrument panel to remind the driver. This situation often occurs in the use of some cars: after the fuel tank is filled with fuel, the fuel warning light is on. In order to eliminate the hidden trouble, many users go to the maintenance station to replace the fuel level sensor. If you encounter this situation when you go out , a cotton thread may eliminate the fault .
After filling up the oil, the float rises so high that the contact between the fuel level sensor and the sliding plate reaches the edge position , and sometimes even disengages . In this way , the resistance will be very large , which is equivalent to the position in case of lack of oil , and the fuel warning light will naturally give an alarm . At this time, wrap a few threads of cotton thread on the float arm limit block of the fuellevel sensor. In this way , when the float arm contacts the limit plate , the contact and sliding plate will not disengage , and the pointer of the oil gauge will indicate that the oil tank is full instead of giving an alarm .
When there is air in the hydraulic braking system and hydraulic clutch system, it will bring potential safety hazards to the operation of the vehicle . To exhaust the hydraulic system according to the conventional maintenance method , it generally requires the cooperation of two people . One person keeps pressing the brake pedal or clutch pedal in the cab, and the other person screws the oil drain bolt under the wheel or under the engine to exhaust. This method not only wastes manpower and material resources, but also the repair quality is not necessarily guaranteed. Medical syringes can be seen everywhere in pharmacies or clinics . It is a measure to turn waste into treasure to use waste syringes in the exhaust of the hydraulic system of automobile maintenance . The conventional method is to exhaust the air from the main pump down or from the sub pump up. In fact, if the air is discharged from the sub cylinder to the master cylinder or from bottom to top, the same purpose can be achieved .
