So for the past few days i have been noticeing a strong smell or raw gas around my car. Today i noticed a small puddle underneath the filler neck to the gas tank. Under inspection i saw that the tank where the filler neck connects to it, is leaking. How does the filler neck connect to the tank? and what are some options on how to fix it. i was thinking some sort of gas resistant RTV, or gas tank repair stuff. Any ideas?
