boat fuel gauge sender unit
The boat fuel gauge sender unit is in the oil tank. The fuel quantity of the boat's fuel gauge is transmitted to the instrument panel through the level sensor in the fuel tank. If the fuel gauge does not work , replace the boat fuel gauge sender unit in time . Don't wait for the alarm light to come on again , because the gasoline pump is in the fuel tank , and it relies on gasoline for heat dissipation and lubrication . Too little oil is not conducive to the normal operation of the oil pump and reduces its service life . It is not recommended to top up when refuelling , because gasoline expands and volatilizes into gasoline vapor under high temperature in summer , which requires an empty space to contain . If there is no empty gasoline vapor or even liquid gasoline when the fuel tank is filled , it will enter the carbon canister for storage . After the carbon canister is filled , it will escape into empty gas , which will not only waste but also pollute the environment . If there is any deviation in the indication of the oil level gauge , when the ship starts again , you may notice that the oil gauge pointer is lower than the previously displayed position , which is considered as a fault. In fact , it is a normal phenomenon, because there is negative pressure in the oil tank when the oil pump is working, the volume of the oil tank decreases accordingly , and the oil level is high. In addition , due to the heating effect of temperature on gasoline , it is naturally high. When the temperature drops and the oil tank is opened, the pressure is released and the oil level drops accordingly , so the deviation is normal . However , the deviation generally does not exceed one pointer width .
The boat fuel gauge sender unit sensor is always immersed in the fuel tank, so if the immersion time is too long or the fuel quality is poor, it is easy to make the sensor surface adhere to sludge or other dirt. The solution to this problem is relatively simple. The fuel gauge sensor can be removed for cleaning and adjustment. If it needs to be replaced, it should be replaced in time .
