Haha, I'm not wrong. But I have better things to do than argue about this.

Regards,

First of all, Jim (jiott) explained that the different lengths of the feed lines on the left & right tanks and the ID size and flow rates that we are talking about, are a non-issue for all practical purposes - no measurable frictional difference. I believe that Jim is a retired engineer who dealt with hydraulic design for a living.

Secondly, Jim & I both explained that the vent line does not and can not feed any fuel to the header tank when the level in the wing tank is below the level where the vent line connects to the wing tank (which is up at the very top of the tank of course). The feed and vent lines are not a set of "double lines" that are both feeding the header tank.
