Sorry Grit. For taking so long to look here again. The fuel cap in the 06 does not leak with the head of fuel above it. I ran all fuel through slip tank so that it was pre filtered to the main. The main fills and air/fumes escape through a valve on it. When fluid reaches the top it must have a floating ball in the breather that prevents fuel leaking.
