Hey guys, I need some quick help on something very easy. I've got a valve leaking on my passenger front. It's leeking where the two valves meet up at. I've 1/2 up 3/8 down and it's all done with 1/2 inch line if any of that matters, just in case that changes the size of the wrenches I need or anything. But, I need to know what the proper way of tightning these would be so I don't tear them up or anything. Thanks guys.
