I cant seem to figure out what to do with the pipe that comes from the back top of the block and leads down next to the oil filter. I have the pipe...but nothing to plug it into...I believe it is supposed to go to a cleaner...which I dont seem to have, where is it supposed to go after that? I dont see anywhere for it to go. On this picture it is listed as (pipe, and cleaner 1.762) Please help!! Thank you!
