Lawn sprinkler leak on my Emag, do I....

[CFD323]

I'm getting the lawn sprinkler leak on my Emag. Do I just need to replace the black quad o-ring to fix it ? Or do I also change the power tube o-ring too ?

If I remember correctly the "lawn sprinkler" effect is caused from a bad on/off oring. The one that seals the top of the on/off pin.

Only o-ring to replace is the quad (black) o-ring.
