----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- I know my brain doesn't always work correctly. Some of you would say, "that's because I don't have a brain" But, This doesn't sound right for me. Let me see, fuel flows down hill, vapors flow up, which in general makes the Coupe Vapor Lock resistant for at least 6 gallons. Could the wing tanks vapor lock? Perhaps, but as there is only one line from the fire wall to the pump, there should be less chance of vapor lock there than most planes. Could happen of course, but if you see your header gauge going down before it should, regardless of the cause, you should look for a landing within 45 minutes.
