Be forewarned, this is probably a very stupid question. But I’m setting up my buffer tank and have a question about the bulkhead fitting. Does it matter which side goes to the inside? Does the actual fitting go on the inside or just the nut? Or does it matter? And what about the washer? There is only one rubber washer so does it go on the inside or out? I think I’ve been in the heat to long today but my mind is drawing a blank. Thanks in advance.
