They are 3 fuel lines on each side of the engines. They look like 1/4 inch lines that come from the block,where it mates to the head. They alternate and go into different corresponding nipples right across from where the carbs are. I tried looking through my manual , but they're not specific and the Bombardier site is temp. down. There are nipples on each side of the line and the lines are only about 8" long.<br />2001 150 V6 carb'd.
