    In your own MK IV, do you have the 2 tanks installed?

    I did read the whole thread about the similar case that happened to Gfry.
    I think that having the header vent closed or open should not make a big difference in a twin tanks system once one of the tanks is empty- because the empty tank gives a direct access to external air in the header tank? (or worse with a forward facing tank vent on the cap will feed air with a positive pressure in the line!)
    By the way, sorry for the trouble with your bird. Hope the repair is in good way!

    In fact, I have the standard Avid header tank installed (I named it "feeder" in my original post), and ram air tubes on both sides. This header tank is installed on the right side, so the tube length to the right tank is shorter than to the left one. I already noticed that the right tank empties a bit faster tan the left one, but I wrongly supposed that normal flow would continue with one tank empty.
    By the way, being a looong time glider pilot, outlanding is quite a common event for me!

    Engine out outlanding
    Hello all
    My plane is a '95 MKIV with the twin fuel tanks option.
    Yesterday, coming back from a 100mi roundtrip, at 5 min from my home airfield, my motor gasped three times and stopped. The outlanding in a large harvested wheat field was uneventful.
    After landing, I found that the fuel line and fuel feeder were empty, although I supposed having at least 15l of fuel remaining. Looking further, I saw that the right tank was empty, but the left one contained still about 15l.
    After adding 10l in the right tank, the engine was restarted and I could return safely to my home field.
    Both tanks are connected simply by a Y fitting without a selector. It seems that when one of the tanks is empty, the pump sucks air in and the fuel feeder and fuel line become empty, leading to engine stop.
    I am glad this happened over an open field!
    Is that a known problem?
