Where's the red ball?
Looking for that last drop of gas at the very bottom of the tube!
It's tough finding a ball that floats, and doesn't go to pot in gasoline. I gave up looking, buying and testing. The level is easy to see when I'm climbing aboard. You would have to bend double to see it once you're seated, anyhow.
This is one of the best accessories I have. I hardly ever run out anymore.
Yes, that's a tire pressure gauge next to it. If you have brass, you should show it.
Here's some photos of one I forgot I had brand new in it's original box with instructions and it has it's read ball in the tube.
