Fuel Injector LIM O-ring
 

Hi guys,

According to the Mazda parts catalouge there are two o-rings in the LIM where the secondary injectors go. I removed my fuel rails and removed the rubber grommet but could not find a o ring beneath it.
Do I have to remove the diffusor to get to the o ring?

There is 1 rubber insulator and 1 oring. The oring goes on the actual atomizer.

can I remove the oring without removing the atomizer?

No. You need to carefully remove the atomizer and often they break. Use a pick, wd40, and gently remove it. If any breaks off be prepared to vacuum out the intake. I recommend buying new ones as they get brittle. It will come with a new oring.
