I'm getting ready to replace the injectors on my 7010.  Are there o-rings on the injectors?

The new ones have a groove about half way down, looks like it could be for an o-ring.  I do not see o-rings in the packages of injectors.

Anyone know where I can get these, and maybe a part number?

Thanks, 
Roscoe.

Drain the antifreeze before removing the Injectors.There is a copper seat / tube that seals the injector
Allis Chalmers still exist in my mind and barns

BECAREFULL, the copper tubes are swedged in the head.  Gently wiggle, tap add pentatration oil etc to loosen - DO NOT force out if stuck.  Removal of copper sleeve = $$$$$$$  -  Clean the head, loosen the retaining bolts and retainer and gently move the injectors back and forth - there is a injector removal tool - but I hate to use it as a stuck injector will be removed along with the copper sleeve.   No seals at the bottom or orings, there is a rubber dust shield around the top.  - pick up a bolt for the drip line and the little sasher seals  as you may pop a bolt when tightening - new ones are not hollow and thus stronger - they do not have to be super tight to avoid leaking  as the drip line is 0 pressure.
