urgent help with sensor HC-SR04

good morning to all, I am working on a project that includes the measurement of fuel level, for which I am using the ultrasonic sensor HC-SR04 and I would like to know the ability of immunity to the relative humidity of this sensor.

thank you for your answers

Surely that's a question you should ask the makers?

I would be more worried about how the sensor reacts to the fumes from the fuel and visa versa.
