edc ?????????

im going to run a york on my caddy and have a few ?i know they run pretty hot and going with steel line someone said run 1/4 brake line but that sounds small but since it runs at high rpm should fill pretty quick?other ?? is....... they have to be filled every so often with oil is there a way to have a return line run from the seperater and be pressured so oil flows back to comp. so it will have a some what mantinace free setup??thanks for any help

kilby sells coalescing oil filters with return lines. I just use an unloader check valve and it has been keeping my oil consumption down.
