Hello So last year I had a problem with my mustang and the gas nozzles at gas stations. It would start to fuel an then the nozzle would click every 5 seconds with the gas spilling out everywhere. So I went to my local mechanic and he said I needed to buy a new gas tank and a new filler neck. I bought those two things and now the gas doesn't spill out but the nozzle keeps clicking. IDK what else I need to do pls help.
