Default Indy 500 oil and vent lines

1989 Indy 500 - what is the CORRECT size tubing for the oil line from tank to motor, and what size for the vent tubing coming off the carbs?? Are you guys using regular poly tubing or are you using Tygon tubing? thanks

I am going of memory, but 1/4 for the oil line and 1/8 for the vent lines. I use tygon for all my stuff. Lot of poly on customers if they don't want to pay the extra for the tygon. You will know if it's right if it fits the nipples tight.
