i actually used jb weld on a gas tank lasted 5 years until i sold the car, this is on a 318 intake eddy lb4d, its on the outside next to the vaccum port tap, screw it i just did it. hole was the size of an ant. Let it dry for a week.
J-B weld will work in an intake, if done as suggested above , it wont be under gasoline all the time like in a carb.
Moroso 2 part epoxy is made for repairing intakes and such. I`ve used a few times in intake runners , and in an alum. head successfully , but does need something to adhere to also...…….
