1969 charger power steering cap

Probably a stupid question, but how tight should the cap be on my power steering reservoir be?  Trying to troubleshoot a leaky system and I know I probably need at least a pump anyway but it keeps bothering me how loose mine is....

I replaced mine last year with a used one on ebay and it was much tighter and fixed my small leak from the cap. The one I replaced definitely felt too loose and was weeping a small amount of fluid.
