    My Onan genset has developed a fuel leak – pic attached.

    Any suggestions of whether I should retighten those fuel lines, and how tight I can go?

    Is there some sort of seal or gasket I can replace if I take them off.

    After a little searching, seems like its common for the o rings to go bad on the delivery valves, so I suspect thatā€™s the culprit here.
