Sorry, I can't get a photo but the reservoir has the two lines out (at the base) and one line is leaking and it is loose with some sort of gasket as a seal. I cannot tighten or unscrew it to see what kind of seal is needed. The inside has a divider and it does not allow a socket to catch the interior nut. Hope this description helps and someone will have had this problem before and has figured it out. Dale
