I'm all for big hoses but there's no particular benefit in a -12 line when the oil pump is feeding it through a 1/2" passage. The oil feed is only as good as it's smaller diameter, by and large.
So here's the left galley feed line...it's 1/4" tubing which has an ID of .200 (or so) and it should be plenty to feed the left side upper end. The fittings are 1/8"NPT SwageLoks, I did have to 'bore' them out from .187" to .200" to match the tube size.
