What size internal fuel lines on 1988 110 Bubbleback?

[kazeej]

I have replaced the fuel lines from the tank up to the motor. The last time I had this motor out, it was hard to start, but would run fine after it started. When I got back, I took off the cowling, and saw some fuel pooled under the carbs. I want to replace all of the fuel lines from the connection at the cowling to the carbs. It looks like there are different sizes, depending on where they run. I can't find anywhere what size these fuel lines are. I did some searches thru the forums, but I didn't see anything.
Any idea what size these fuel lines are, or where I could find this?

Thanks for any advice!

I belive the main fuel lines are 5/16 and 1/8 on the primer lines.

Yes! That's exactly what I needed! I found a supplier here who deals only with hoses. I'm gonna go buy about 3 feet of each tomorrow. I was going to go in and remove a small piece of each one so I could match the sizes at the supplier, but I was afraid of getting confused on where they went later. I've been working on cars for years - but boat motors scare me...

Thanks!

BRP lists the carb fuel lines at 5/16 ID and the line to the primer at
5/32 ID.
Don't be surprised if one or more of the lines are preformed so you might have a bit of trouble bending them without kinking.
