There's no difference between I filled the car with fuel and I filled up the car with fuel, except that the up implies filling to completion.

I eat.

There's no more space in the thing that you have filled up.

This also works with food.

Imagine you get to someone's party and they say There's plenty of food.

Fill yourself up and of course, you eat and eat and eat, and then they say, Have another piece of cake You say I can't.

I'm full up.

I'm totally full of food.

There's no more space Now let's talk about fill out.
