If your Mfgr. says:

That motor's 7 years old!!
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Part's at central warehouse, you'll get it next month.
We don't make parts for those.

These kits DO NOT include the 2 o-rings (in RED in the exploded view above) between the oil mix unit and the body of the VRO pump.
Normally, you DO NOT need to remove the oil unit; it is not serviceable and there's no reason to remove it unless it's leaking.

If you do remove it, you WILL need this o-ring kit
The originals will be distorted and will leak
