OK, I guess I'll show my ignorance here... does it really matter? You hook it up one way and the FEL goes up when you push/pull the lever or it goes down. Just have to remember which way it is on your tractor. If it bothers you that it seems backwards then simply reverse the fittings. Would not lose too much sleep over it, but then I am just too busy with other things than to worry about this when reattaching my accessories.

well its a little more complicated than that. i'm plumbing hard lines to my SCV's so i have to make sure i have the correct ports on both valve bodies. no way to just take them out and flip them. and there wouldn't be anyway to tell the power beyond from the return to tank.
