The only issue I have after looking into this all day is the availability of 3/16 copper pipe and fittings. Not very common around my parts unless I am not thinking of an obvious supplier. For about 15 bucks I could adapt the oil distributor side and rocker side to 1/4 copper making parts and compression fitting common and easy to obtain anywhere. Someone on this forum has had to done this themselves with common materials. Hmmmmm.
