Rear engine fuel drains

[n86121]

1. Can anyone identify the various drain lines as below?

When topped off I have a steady drip from #2, at least.

If I can find some time will follow the lines up to wherever they go, but I thought others may also find this info useful.

From research, the fuel divider apparently has a 4 psi cut off that may not be cutting off, thus draining into and then from cylinders out the drains?

2. An A&P years ago routed my oil breather (fire sleeved etc) down and out as number 7 in the photo, to reduce breather drool onto rear elevator. After a long descent / flight I sometimes find drool on the cowl, apparently slimed up the passenger side by airflow.

When filled to only 6 quarts everything stays nice and dry. I filled to 8 for this weekend of 7 hours flying and noticed the drool. It is still at 8 qts, so maybe the answer is to leave it at 6 and only bring up to 6-7 when down to 5 qts?

a. Would I be better off with the breather NOT in the airstream,
as it may possibly be sucking out air/oil in its present position?

b. Any other recommendations?

Thanks
