My fuel cap seems to be leaking (XH ute), it usually happens where there are right-hand corners - take a few hard and you can just about see the fuel gauge has gone down, sometimes also on bumpy roads, and it is worse when it's full. As my id suggests it's an Outback ute, which are apparently meant to have a different fuel cap. Does anyone know what the difference is and if it matters? Is leaking like this a common problem? Could it be something other than the cap? Have I asked enough questions yet?
