APD secondary float setting?

Anyone know what the float setting on an APD 4150 billet enforcer secondary should be? Have had no luck getting through their phone line the last few days. I have been setting it with the sight glass, but I would prefer to set it correctly. Thanks.

With the bowl upside down set the float so a 3/8 drill bit will slide between the top of the float and roof of the bowl. Some also set using a 7/16 drill bit, which would give a lower float level. I set mine somewhere in between around 13/32.

Yep. I use the 3/8 bit for reference but I like to go a flat or two lower than that.

Randy at APD told me to use a 5/16” drill bit. Good luck

not sure if any of those measurements will work. If I could figure out how to post a pic,I could show the float is much smaller than the ones I'm used to. I finally got through to somebody at APD and he said 1.004 from the top of bowl on the pump side to the perimeter line on the float. Thing is there is no line!! Arrrggh. I'll try again tomorrow or just go back to using the sight glass.
