I have a gas tank leak for some reason, got it fix 2 yrs ago by buying a tank but its leaking again. There is no crack in the tank so im wondering is there a seal around the fuel pump that is causing the leak or is it a gas line?

most of the time its the fuel lines that are leaking, not the tank itself

i dont think so... did you trace where the fuel is coming from and what lines you need to replace? there are two lines that come out of the top of the fuel pump and then route to the front of the car. you need to verify where the fuel is leaking from before you can fix the problem (who knows if its the fuel check valve, the lines, the tank itself that is leaking, thats the first step of diagnosis )
