If that is a 40 series TC with the standard spring in the driven, the driven unit should be flipped around.
If it needs to be that way, it needs a reverse wound Yellow Spring and should float.
If it is not a 40 series or already has a reverse wound spring, then carry on.
This is an amazing build! One question that came up going through this is, have you considered where your electronics will go? I believe I spied a starter cable on your motor, but I don't see much room for your battery, wiring, etc. I assume you will have electrical, mostly because those light bars require some amperage. I only ask because I needed to address this problem on my build as well.
Well, considering it looks like your petcock is in the front, not sure I see an issue with it being crooked. With it being tight to the frame like that, it looks intentional and functional in design. I would stick with that tank, I like the shape and size.
The photo is deceiving, the petcock is centered on that tank. I wish it were in the front, I would have used it. I didn’t see your response till after I purchased another tank. I found a new spun aluminum tank that is American made, 6 gallons too. It was a touch pricey, but I think it will look great when I’m all done with paint on the frame.
