I'm going to try liquid copper first on a suggestion from someone who used it on his truck. Right now, it's hardly leaking. Only drips slowly when the car is running. The new rubber O-ring on the tube didn't get in straight. I can see a little of it poking througn on the edge. If that doesn't work, I'll have to drian the system anyway. I will have to pull it apart again. I'll try the tube first. My 84 had some play in the tube when I did that one a few years ago. This one won't move. I may have to bend it. The pump sealed so well I'm afraid it will leak if I pull it off and reinstall it + it's a pain to remove.
I'll let everyone know if "Liquid Copper" works or cruds up the system.
