2004 Chevrolet Trailblazer Ls pouring gas out top of tank
 

We have replaced the fuel pump but now it's pouring fuel from somewhere on the top of the tank, but then it will stop pouring it out and be fine for days and all of a sudden it will start pouring it out again. Help please

did you install a new fuel pump gasket?

Yes and the new one leaked and was a lot smaller so we replaced that and we still can't tell where the leak is coming from. It is still leaking if we let it sit it stops leaking and you can drive it for a little while. Then all of a sudden you'll smell gas and it's leaking again. :(
