How to Solve High Fuel Tank Pressure?
1 Answers
High fuel tank pressure is usually caused by a clogged fuel tank cap regulator valve or a blocked charcoal canister vent. Use a vacuum pressure pump to check whether the opening pressure of the fuel tank cap is within the normal range. After identifying the cause, exhaust treatment can be performed. Since the fuel tank is filled too full, the remaining space inside the tank is relatively small, so avoid overfilling with gasoline.
