Difficult repair but doable. The old line dispensed heavy liquid. I just cut off the old rusty lines with an oscillating tool and a 1/2" nut on the top. Too bad I didn't do that on the bottom too. I removed the bottom part but was able to use the IRWIN Bolt Extractor Kit 5pcs (394001) get out Don't forget the 2 washers that come in the kit I haven't seen them but my wife asked if I need them good catch it doesn't seem to be flowing.
