OK Whit,
If I add in 2 stroke, what type should it be, ashless or just any old type and should it matter on the name brand etc.?
I've been using ULSD for about 18 months now (maybe longer) and it has been about 12 months that this weird idle and funny sounds have been around intermitintly.

so it does it when the tank i low and then it goes away when you fill it up? could be that your pickup tube has a small crack in it close to the bottom and you gettin slight airation in the fuel and its causing that. it but i dont know with a fass cuz those are suposed to have air seporators.

Did you install a draw tube?
Since the noise increases at low fuel levels, I am betting the pump is cavitating. No amount of air removing technology will stop the air hammering sounds.
If you are using the stock module, it is one of the most restrictive years made. Low fuel level creates a higher vacuum load and causes cavitation much easier.
If you are running a draw tube, double check the connections including the hose to draw tube fittings as this is the most common point of sucking air. It is possible as the level of the fuel decreases, the pump must work harder to fill the inlet. And if you're sucking air, it will aerate and that'll sound like cavitation as it enters the pump.
I just had a buddy with a pump that started making noise. He was convinced it was a bad pump. Turned out to be a bad connection at the dorman (tank) fitting. It's a place to start. Then check every fitting and connection on the suction side.
I respect others opinions with additives and oils. I choose not to run them for my own reasons. But keep in mind you say you have had ULSD for about 18 months. Most likely its been far longer than that as most of us have had it for at least a year prior to it's official release.
Stick with the easy stuff first.

As for the 2cycle oil... yeah... give it a shot. I buy the little pint bottles at wallyworld. I just dump one in per fillup. I've got a long bed, so I've got the big tank. Just that one little pint makes the motor MUCH smoother than without it. My fuel station still doesn't carry ULSD ( ), so if you're filling with that, you may require more.
