1988 Vulcan 750 California model. But I changed thetank from a non California What size id are the rubber fuel lines and the vacuum. Could the right carb be different than the left side? I think the nipple elbow shown in the background is fuel and the straight one in the foreground is vacuum? The hose (which broke off and I have to replace it) is the left carb fuel? Are there premolded hoses you can buy or just use neoprene hose?
