I am not sure where the o-ring sits on the bottom of a RC injector. Could someone please explain or post a picture? I don't want to put it back together incorrectly. Thanks!

 

Does this help?

 

Thanks! Yeah that helps. My RC injectors came with different o-rings then the ones above. I have a single large o-ring per injector (similar to OEM) -- yours looks like there are two smaller o-rings.

That is actually where I had mine, but I'm having a problem seating the injectors with the o-rings in the intake.
