What if there is fluid coming out of the vent hose?

If fluid is coming out of the vent hose, it may indicate an overflow or malfunction in the system it is connected to, such as a fuel tank or drainage system. This could lead to potential leaks or contamination, which should be addressed immediately. It's important to identify the source of the fluid and stop any further leakage to prevent damage or safety hazards. Consulting a professional for diagnosis and repair is advisable.
