Hi, If I remember, I usually make up a tee out of copper using 1/2 in and out and 3'8 out the side. I use 1/2" rubber to the rear of the car. The MB hoses push over the 1"2 copper good and the 1/2" rubber hose slides over the 3/8" hose. Don't use plastic sprinkler fittings. The heat distorts them and they leak.Also when you make up the T for the oil filter area leave enough hose so you can still get canister lid off
