The one with the filter (second from the front of oil tank) goes to the oil pump nipple that is closest to the middle of the pump or towards the center of sled. The one with out filter (first from the front of oil tank) goes to the oil pump nipple that is on the outside of the pump or towards the right side of sled. Send me your email and I can send a copy of the wire and pipe routing from the service manual. cccsche@gmail.com

Remove the Phillips bleed screw on side of pump and let the oil run until no more air comes out. Then locate the oil pump adjuster in the middle of the oil pump cable, start sled, let idle, then pull the two halves of the cable apart which runs the oil pump like you would be at W.O.T. until it smokes like crazy which will tell you the oil lines are full ! This can also, be done when putting the sled away for the summer to give the engine a good coat of oil !
