Card for showing Liquids (fluid-level-background-card)

The very first post is about a similar case.

So I feel like I am close,

But its filling the entire card still. My image is now transparent inside the gas tank.

Its not just filling inside the tank, the whole card background is filling?

Any ideas?

Thanks

You need to use picture-elements card like was proposed in the 1st post.

How do you get rid of the overlay on the outside of the card (specifically Mushroom)?
