If everything is working and it were mine I would just drive it for 6 months. What's the old saying if it ain't broke don't break it. Those fitting in brass look like they came from someplace like Lowe's plumbing department. I know that connection does not meet your standards and I understand that but there comes a time when you have to turn the key and just enjoy the drive. My son is very particular about his vehicles and the slightest scratch and there off to the body shop. I told him one time to forget it because at 100 feet and 100 MPH nobody will see them. I don't know about Florida but here nobody has ever come up to my car and jacked it up to look at the underside.
That's not to say if it is a poor place for those lines to be run then by all means you will have to figure something out.
