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.

No orings are needed the injectors should seal to the tubes in the head Niel

Drain the antifreeze before removing the Injectors.There is a copper seat / tube that seals the injector

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.
