How do you fuel up?

[Django]

I'm sure you're right. Same tank. I wonder why it would be different? I believe there have been others that have stated the problem. And believe me, you would know what I'm talking about if you had it. There is no denying the tank fills up, drains down to just below the filler, and then takes more up to the top, and repeats. I know for sure I have repeated this 15 times and still could take more. Even on the centerstand. I've never had the patience to see just how long it would take to have the tank completely full. Like I said, it's not a huge deal, it's just inconvenient.

Maybe the U.S. tank has a different filler neck. That's the issue I've observed on mine. The filler neck extends about 1.5" below the top of the tank. As the fuel level reaches the bottom of the filler neck, it will fill up the neck first. When the fuel flow is stopped, the fuel drains out of the neck to the level inside the tank. Basically, what you're doing as you try to top off is repeatedly filling the neck, then waiting as it drains into the tank.

I hardly ever bother trying to do that. I experimented once and found the difference between filling to the bottom of the neck and completely topping off was about 2 tenths of a gallon. Not really worth the time and effort unless your next fuel stop will be close to the range of the tank.

I think, the intention of this neck is to stop fueling below the top of the tank. There should me a small air reservoir to allow expansion to adapt to temperature changes.

Filling completely to the top will only drain over filled fuel thru the level drain, which is a small tube ending near the center stand.

Managed to do so once...
