Pinball FX2

This achievement is quite easy and very straight forward.

In the center of the table are three drop down targets dividing the table in half. These spell out GAS. Chances are that when you launch the ball you will end up in the top half of the table and by default end up knocking one of these down. If not just start knocking these down to clear your way to the top half of the table. THIS HAS NOTHING TO DO WITH OBTAINING THE ACHIEVEMENT DIRECTLY, but it obviously helps you on your way.

On the top half of the table you will see three round lights with the letters / numbers N, 2 and O. Each of these lights has a circular target above them. Hit the target to light up the letter / number.

Once all three are lit, a red and yellow triangle will light and direct you to shot in between the N and 2 targets. Hit this shot and the ball will ramp around the right and into the Nitrous tank. Once this happens your achievement will pop. If you take too long, the targets can reset and you will have to begin again.

So again, this one is super straight forward and once you know what you're gunning for will take you absolutely no time at all.

Good luck and happy hunting.

Here's a video I found for those that want to get a visual of Dr Gonzo 815's guide. It shows the achievement unlocking.
