These inexpensive brass quick disconnects are installed backwards to each other also. Without disconnects installed, when I disconnect my tank fuel lines, the return line starts draining fuel out of the tank, unless my fuel line clamp is in place of course.
You put the female disconnect on that end, coming from the tank to prevent this when you disconnect.

The other line (the fuel pump line coming from the tank) gets a male since it only dribbles a few drops when you take the tank off. I put a rag under the lines when I pull them apart to catch this.
You make a drain hose with some old fuel line or whatever and third male end that plugs into the return line to the tank so you can drain gas in a controlled fashion.
The Beemer boneyard quick disconnects are a fine product I am sure but you are still going to need a third set to make a drain line if all four pieces seal up when disconnected. How are you going to drain your tank when you remove it for service? You either need a third disconnect or you need to remove one which takes the "quick" out of quick disconnect.
FWIW, I spoke to SmallParts.com over the phone and they checked with an applications engineer. The Buna-N seals are synthetic and are indeed suitable for gasoline and other petrochemicals.
