sanden grease conversion question HELP!!

does anyone know if this hole that i am pointing at in the picture is the one that needs to be tapped an plugged for the grease conversion?
thanks

flip it over and take another picture

BUMP! anyone?

looks like thats another part of the outlet... you can tap and plug it

yea, it looks like some kind of vent. Andrew, i noticed your compressor does not have that.
i dont even need to tap it, its a 3/8's 24 thread so i am just going to put some sealant on a screw or set
screw and be done.
