Hi there. I hooked up my fuel line to the fuel tank, to the filter, and to the carburetor. Only problem is it leaks. There's no hole in it. The problem is the seal around the ends of the tube. It's not water tight and gas leaks through them. I literally just pushed the tube down on the filter ends, on the petcock, and on the carburetor fuel entrance. It was tight but not tight enough. What can I do to make it water tight? I was thinking some silicone caulk? Or is there some kind of thing I can wrap around the seal to make it really tight? Please let me know.
