There's a pin hole leak at the rusty fitting you see in the picture: http://imgur.com/a/INaGU
The leak is JUST below the rubber hose. I believe this part cannot be replaced easily. I was thinking of two options:
1. Cut the top off. If I do this, how worried should I be from metal shards from sawing it to fall into the manifold? How would I make the top of the nipple wider so the hose would be snug in there?
2. JB Weld the hole and push the hose further down and put a new clamp on the hose.
What would you guys suggest I do? The hole thing is rather rusty
