Put on my oil cooler, it started leaking a ton from the banjo bolt. Took it apart and realized there was no o-ring in the assembly (part #4). So I ordered a new one but it's a lot smaller than the copper washer (part #5). I'm not sure where this little o-ring goes. I'm not sure if I just got the wrong part or what.

Where exactly does that o-ring (#4) sit in relation to the housing and the banjo bolt?
