Injector seal confusion

Bought a set of injector o rings for my 2003 2.4 NA v70. The o rings are 2 different sizes. One seems larger and a bit thinner wall, the other is a smaller looking ring and thicker. Could someone let me know which one goes on the end that fits into the intake(not into the fuel rail)? If it helps, they are green injectors.

If I remember well the larger one goes on the top, smaller one near the nozzle. Good to make sure the environment is perfectly clean, including around the manifold. Smallest dirt particle near the seals and it will leak

Vaseline on the seals a must to reinstall (same for the FPS sensor)

Thank you for taking the time to reply. Went with the thicker ones and no leaks.
