I have an 2001 mustang and that stupid discontinued part the holds the gas tank pressure regulator on is leaking when gas is filled into and because of the leak fuel level wont work either. And yes it was working fine and I just replaced it before the seal went bad. I tried to fix it with rtv and it worked that is until the gas got to it and started leaking. Does anyone know like a fuel resistant silicone I can use the seal the regulator to the gromet without it coming undone from gas. I just dont want the rubber to get eaten up.
