Fuel pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than ambient pressure.

The pressure gauge uses the elastic deformation of the sensitive elements in the watch, and then the pressure deformation is transmitted to the pointer by the conversion mechanism of the movement in the watch, causing the pointer to rotate to display the pressure. It can be seen from the above that the pressure gauge is an instrument used to measure pressure. If the instrument fails during use, it should be repaired and deactivated in time.
1. When there is no pressure on the pressure gauge with limited nails, the pointer cannot return to the limit nail after the pointer rotates; when there is no pressure on the pressure gauge without nails, the zero value of the pointer exceeds the allowable error specified by the pressure gauge.
2. The surface glass of the fuel pressure gauge is broken or the dial scale is blurred.
3. The seal of the fuel pressure gauge is damaged or the validity period of the calibration is exceeded.
Fourth, the fuel pressure gauge leaks or the pointer jumps.
