I would want to find out where it's leaking from.
Locate the pump and start there. There is a pressure line and a return line to consider then there are fittings and crimps any of these can be the source of the leak. You're just going to have to search for it. I understand how difficult it could be but if you know the source before you go in to have it repaired you are less likely to be "sold a bill of goods" and it may be something you can repair yourself.
