How to Check Your Boat’s Fuel Tank

To ensure your boat’s fuel tank is in good working order, it is important to regularly check and drain it as needed. You will want to check the tank for any signs of leaks or cracks, and if any are found, you will need to repair or replace the tank as soon as possible.

It is also important to keep the tank clean and free of debris, as this can clog fuel lines and lead to engine problems.
