Got my header tank from Viking today. Looks nice. Includes all of the goodies to hook it up, even. Only one problem. The sight gauge is on the wrong side. When you install the header tank as designed in front of the passenger seat, the sight gauge is completely out of sight of the pilot. In fact, it’s almost out of sight of the passenger. If it were on the left side of the tank instead of the right, it would be equally hard to see by the passenger, but at least the pilot could see it. Oops.
