If the top leg of the sight glass has a segment that droops down, it can get fuel in it which forms a loop seal, just like the loop seal in a toilet or kitchen sink. You can also have problems if the lower leg of the sight glass and the engine supply use a common tap into the tank. This is not a common problem but it can happen depending on the flow characteristics in your lines.
