Once a light reaches the end of the path, the pressure is counted.

Keep in mind that if you dump 10 units of fuel at once, each unit must travel behind the other, single-file.

I'm assuming what this line means is that if you dump 50 units of fuel into the boiler, the rate the fuel moves through the STEAM PIPE is faster.

The lights in the steam pipe are just for show, the points are awarded when the fuel (ball) goes through the sensor.
