where are you getting the feed from?
here's what i did on mine
TEE off the sending unit on top of the block. 90 out of there to a -4 line to another 90 on the turbo.
then i had a -10 return line going as straight to the oil pan with only a 45 at the bung on the pan. bigger is better on the return
never smoked! and as far as i can tell its not smoking on Kian now either
