I got mine on using a 5/8" deep-well socket. It is a 6-sided socket, so the walls are thin. I got the whole thing installed in about 30 minutes, fired it up, and oil gushed from the banjo fitting stack. I re-installed it at least 20 times. I finally deduced that it is critical for the banjo fitting stack to line up correctly. I got some crush washers at AutoZone with the same inside diameter as the ones in the kit, but with a slightly larger outside diameter. That makes it easier to see the edges of the washers, to help line things up. I had a mirror behind the stack, and a spotlight, and I used a small screwdriver to nudge things around. I had some problems in that when you get them lined up they move when you tighten them. I went for a 100 mile ride, and when I got back I took a paper towel and swiped it around the banjo stack. There was only a slight smudgeon of oil. I thought about installing it again, but I believe I will leave well enough alone -- at least for a while!
