The correct ball was made of hard plastic or rubber and was the same density as gasoline. It melted either from heat or fuel. the ball needs to be opaque. The ball in the photo is for illustration purposes. It is from a straight pin and the wrong material. I am looking for a black 0.250" glass or plastic ball.
the light source failed and I am going to replace it with a LED. But even with a ball bearing in inside and my flashlight, I can get the display to count fuel by blowing thur it.
I am going to put it on my mechanical injected diesel.

Hi Diesel John,
You should familarize yourself with McMaster Carr. They have all kinds of interesting things in stock. You could spend all your time browsing their products.
See the following link for plastic balls.
McMaster-Carr All types of plastics. Polypropylene should be perfectly resistant and what you need.
