I have a TJ40ELESR that is leaking fuel from the fuel intake line. As I was attempting to remove the fuel hose, the nozzle came off. It looks like it was designed to come off but I'm not sure. This was also the place where fuel was leaking out.
There was also some milky substance around the nozzle. Is this oil/water mix?
