2003 Nissan Altima 2.5s code 0442

I bought this used car and it has 140K miles. A few days ago I got the 0442 code and thought it was a loose gas cap. I tightened the cap and cleared the code. A few days later the code returned and I smelled gas and saw a small leak around the gas tank.

Today the code cleared but I could still smell a faint gas smell. My guess is I have a small leak in the lines somewhere.

Does anyone know how to fix this? I tired to search the forum but didn't get a clear answer.

Without seeing the leak, it's hard to give advice on what you need to do. The fuel sending unit is accessible under a panel below the rear seat cushion, so it may be worth pulling it and see if you can see the leak from there.
