Ok so I just replaced my fuel pump and I put in a Isis pump and ever since I've noticed when I fill the tank completly till it stops and clicks there is a fatty leak. But the leak/flow doesn't start till I remove the gas station pump. I really need help I'm stumped. And when I pull my gas cap off I don't hear a hiss. Could this mean the pressure valves are faulty?

So far I have replaced the giant o ring on the assembly
checked 2 main feed and return line for leak when connected at assembly
Also checked the neck if it was tight and secure
