How are you getting air in the system? Is this from startup or somehow getting in during normal ops?
I'd be leary of putting some type of an air eliminator on a HC system. If it failed, you don't want to be venting kerosene out of it.
I'd look at identifying how the air is getting in there (which you may know) and stopping it there.
As a general rule, air and HCs always makes me uneasy from a safety point of view, not that kerosene is highly flammable but still.
