I have some questions about the Van's fuel selector switch.
(Disclaimer: I'm gonna use it so for those of you that want to convert me, thanks, but not right now, I'll swap it out later should the need arise).
Anyway, on the plans, DWG 36, RV-9/A, the location of the switch with relation to the the rest of the forward fuselage is shown. The fuel line coming in from the left tank crosses under the selector switch and connects to the opposite side of the switch and the same is true for the right tank fuel line. The lever on top of the switch has a long arm on one side and a small point on the other. With the switch mounted per the plans, the long part of the lever points forward and to left. I believe the intent is to have this long arm indicate fuel coming from the left tank. The short part of the switch (with the little pointer on it) faces aft and right while the long part of the lever points forward and to left. It seems to me that a better way to install this selector switch would be to rotate it 180 degrees and let the short part of the lever, (the little pointer on the end), point to the proper tank that fuel is being pulled from. A simple "L" and "R" on each side of the mounting plate would suffice for keeping track of which tank your on.
Here are the questions.....
Does anyone know the logic as to why Van's designed the Fuel valve mount setup the way they did?
